Visual deception. Carefully! The coolest optical illusions of our time! An incredible collection of pictures and animations
The coolest optical illusions! They will help your brain switch gears and take your mind off things a bit, but be careful: as we know, overdosing on medication can be dangerous!
Here is a simply incredible collection of modern optical illusion pictures, with which you will spend time enjoying the tricks and sensations produced by your brain.
Optical illusion- an impression of a visible object or phenomenon that does not correspond to reality, i.e. optical illusion. Translated from Latin, the word “illusion” means “error, delusion.” This suggests that illusions have long been interpreted as some kind of malfunction visual system. Many researchers have been studying the causes of their occurrence.
Be careful!
Some illusions may cause tears, headache and disorientation in space.
Pulsating poster
At whatever point in the picture you focus your gaze, the picture never stops moving for a second.
Kaleidoscope
An illusion of movement based on the work of Akiyoshi Kitaoka, a professor of psychology at the University (Ritsumeikan) in Tokyo, world famous for his many illusions of movement.
Eye?
A shot from photographer Liamm, who was filming a foam sink but soon realized it was an eye staring back at him.
Four circles
Be careful! This optical illusion can cause headaches lasting up to two hours.
Ferris wheel
Which direction does the wheel spin?
Invisible chair
The optical effect, which gives the viewer a false impression of the location of the seat, is due to the original design of the chair, invented by the French studio Ibride.
Hypnosis
Stare without blinking at the middle of the image for 20 seconds, and then move your gaze to someone’s face or just a wall.
flying cube
What it looks like real cube, floating in the air, is actually a drawing on a stick.
The Birth of Animation
User brusspup creates animated images by overlaying a grid of black parallel lines over the finished drawing. Before our eyes, static objects begin to move.
Look at the cross in the center
Peripheral vision turns beautiful faces into monsters.
Ordering squares
The four white lines appear to be moving randomly. But once you put images of squares on them, everything becomes quite natural.
Volumetric Rubik's Cube
The drawing looks so realistic that there is no doubt that this is a real object. Twisting the piece of paper, it becomes obvious that this is just a deliberately distorted image.
Same or different?
How can two cigarettes be different and the same size at the same time?
This is not animation
This is not an animated gif. This is an ordinary picture, all elements of which are absolutely motionless. It is your perception that is playing with you. Hold your gaze for a few seconds at one point, and the picture will stop moving.
Aren't you tired? Then…
Brain explosion! Optical illusions on the verge of madness!
Endless chocolate
If you cut a chocolate bar 5 by 5 and rearrange all the pieces in the order shown, then out of nowhere an extra piece of chocolate will appear. Our readers have figured out the secret.
Black and white or color
If you look closely at a point in the center of a black and white image for 15 seconds, the picture takes on color.
Impossible elephant
Drawing by Roger Shepard.
Illusion of color
Without looking up, look at the cross and you will see how the purple spots turn green. And then they disappear completely.
Black and white illusion
Look at the four dots in the center of the picture for thirty seconds, then move your gaze to the ceiling and blink. What did you see?
Interior illusion
Chessboard squares
Are squares A and B of the chessboard different colors? The Color Perception Illusion, published by MIT professor Edward H. Adelson in 1995.
And this one Incredible project designers David Stanfield and Al Boardman. They created web spaces where they invited all their creative colleagues to take part in supporting the project, which was called “9 squares”. As planned, each designer should imagine a 350 pixel square with an animation lasting 3 seconds, using only 4 colors. When finished, the work is combined into 3x3 squares. To the surprise of David and El, their project attracted many like-minded people, regularly adding to the “9 squares” collection.
Incredible optical illusions!
An optical illusion is a trick of human vision. Observations of some images leave visual illusions in our minds.
Optical illusion is the unreliable perception of certain visual information. A person, looking at an illusion, incorrectly estimates its size or shape, creating a deceptive image in his mind.
The reason for erroneous perception is the structural feature of our visual organ. Physiology and psychology of vision allow us to make the wrong final result and instead round shapes, a person is able to see square ones, and large pictures will seem small.
Illusion - error of visual perception
Optical illusion can be divided into several main types:
- incorrect color perception
- misperception based on contrast
- misperception of object size
- incorrect perception of image depth
- twisted illusion
- "shifter"
- illusions that move
- 3D pictures
- optical illusion contour
The human brain can react deceptively to some images. It seems that the image moves or even changes color only due to the fact that the brain perceives the visible light of some pictures.
Moving pictures optical illusion, photo
One of the most popular are the so-called moving pictures. Secret of this type lies in color and contrast perception.
moving picture It is enough to look at the center of this picture for a few seconds, then look away to one of the sides of the salad frame of the image, and the picture will literally “float”.
moving illusion "wall" This illusion can be classified into two types: “curvature of shape” and “moving illusion”. Firstly, the uneven placement of the cubes allows us to conclude that the lines are crooked.
However, they are absolutely smooth. Secondly, if you move the picture up and down using the slider on your monitor on the right, you can see how the cubes move and run.
moving illusion Thanks to the textured image, it seems that the squares in the center of the picture are moving.
an illusion that moves Thanks to the contrasting image of the round disks, it seems that they are moving in different directions: clockwise and counterclockwise.
the illusion moves Patterns in the picture different sizes and stand out with bright contrasting colors. This is why the lines and curves appear to be moving.
What kind of visual illusion pictures are there for children?
- Visual illusions are one of the most popular intellectual entertainments for children. Observing such pictures allows you to develop your child’s thinking.
- He tries to understand why this happens, that what is desired is not presented as reality.
- In addition, groups practice eye muscles. This helps improve blood circulation to the optic canal, which means it serves as a kind of prevention of blindness and other problems.
While observing illusions, the child exercises his logical thinking and develops the brain.
The most popular illusions for children:
animal shifter This illusion helps the child understand which animal is shown in the picture: a cat or a dog. The child analyzes everything external features and remembers the characteristics, in addition, he tries to visually reverse the image, which trains his eye muscles.
volumetric illusion This illusion provides the child with the opportunity to see a three-dimensional image. In order to do this, you need to bring your face closer to the image, direct your gaze to the middle, diffuse your vision for five seconds and then quickly focus. This activity intensively trains the eye muscles and allows the child to develop vision.
mirror illusion Uniform prints located mirror to each other allow the baby to find common features external parameters in different animals.
optical illusion This image allows you to develop abstract thinking: in the proposed picture you can see a simple branched tree. But if you read the contours correctly, the image of a newborn child will appear before your eyes.
What are hypnosis pictures, optical illusion?
Some images are called “pictures of hypnosis” because they are capable of misleading and a kind of trance, when a person diligently tries to understand the secret of the drawn objects and why they move.
hypnosis picture There is a belief that if you look for a long time at the center of a moving image, a person imagines himself plunging into a deep tunnel without a bottom or edge. It is this immersion that distracts him from other thoughts and his trance is comparable to hypnosis.
Illusion pictures in black and white, optical illusion in contrasts
Black and White color a - absolutely opposite. These are the most contrasting colors of all. Looking at this picture, human eye literally “doubts” which color to pay the main attention to and that is why it turns out that the pictures “dance”, “float”, “move” and even appear in space.
The most popular black and white illusions:
parallel black and white lines The secret of the image is that the lines on the lines are drawn in different directions and that is why it seems that the lines are not at all parallel.
black and white illusions These images allow us to see two images in one picture. The drawing is based on the principle of contour and contrasts.
black and white illusion based on concentration In this illusion, for the effect you need to look for a long time at the red dot located in the image.
One minute will be enough. After this, your gaze is averted to the side and on any object you see what you previously observed only on the monitor.
What is optical illusion 3d pictures?
This type of illusion allows a person to literally “break his brain.” This is because the picture displays the arrangement of objects in such a way that, firstly, they become three-dimensional on a plane, and secondly, sometimes they are too difficult to understand.
simple 3D illusion This picture makes it unclear to a person the location of objects: their sides and surfaces. Nevertheless, the drawing is perceived in volume.
complex 3D illusion picture More complex images involve a person peering into the depths of the picture for a long time. It is worth completely dissipating and splitting vision and after some time sharply restoring it.
A three-dimensional figure (in this case a woman) with clear contours will appear on a completely flat picture.
Optical illusions pictures optical illusions
Optical illusions are errors that can occur in our vision. The causes of optical illusions are errors of perception.
While looking at a picture, inexplicable movements, disappearances and appearances may occur. All this is justified physiologically and psychological aspect visual perception.
optical illusion "black dot" The secret of the illusion is that when we notice a small black object in the center, we do not pay attention to our surroundings.
optical illusion "elephant" The unclear image of the contours allows us to see that the elephant has eight legs instead of four.
optical illusion "sun" Contrasting colors and unclear boundaries of the picture allow the image to literally vibrate the moment we look at it and remain immobilized when we turn our gaze to something else.
optical illusion “one picture - two images” Based on a mirror image with exact repetition of all forms.
Optical illusion pictures: dress, explanation of the illusion
- The famous online “virus” and the “blue or gold dress” joke are based on vision perception, depending on individual characteristics each person
- Once upon a time, everyone received a picture on social networks from friends with the caption “What color is the dress?” And many of your friends answered this question in completely different ways: either blue or gold
- The secret to perceiving a picture lies in how your visual organ and under what conditions do you see this picture?
- In each specific case, the retina of the human eye contains a certain number of cones and rods. It is the quantity that plays the role of perception: for some it will be blue, for others it will be golden
optical illusion "dress" It is important to pay attention to the fact of lighting. look at the image in bright light and you will see a blue dress. Go into a dark room for half an hour and then look back at the picture - most likely you will see a golden dress.
Double pictures are an optical illusion, what's the secret?
As mentioned earlier, the secret of this illusion is hidden in the complete repetition of the lines of the drawing when it is mirrored. Of course, this can not be done in practice with every picture, but if you carefully choose the form, you will get quite an interesting result.
classic double picture "old or young woman?" Looking at this image, you need to decide for yourself: “What do you see first?” From possible options you will see a young girl in profile with a feather in her headdress, or an old woman with a long chin and a large nose.
modern double image Among the more modern versions of the double image, we can distinguish paintings that simultaneously depict two separate drawings. In such cases, the features of one image are read in different lines.

People have been familiar with optical illusions for thousands of years. The Romans made 3D mosaics to decorate their homes, the Greeks used perspective to build beautiful pantheons, and at least one Paleolithic stone figurine depicts two different animals, which can be seen depending on the point of view.
Mammoth and bison
A lot can get lost on the way from your eyes to your brain. In most cases this system works great. Your eyes move rapidly and almost imperceptibly from side to side, delivering scattered pictures of what is happening to your brain. The brain organizes them, determines the context, putting the puzzle pieces together into something that makes sense.
For example, you are standing on a street corner, cars are passing through a pedestrian crossing, and the traffic light is red. Pieces of information add up to the conclusion: now is not the best best time to cross the street. Most of the time this works great, but sometimes, even though your eyes are sending visual signals, your brain is trying to decipher them.
In particular, this often happens when templates are involved. Our brain needs them to process information faster, spending less energy. But these same patterns can lead him astray.
As you can see in the image of the chessboard illusion, the brain doesn't like to change patterns. When small specks change the pattern of a single chess square, the brain begins to interpret them as a large bulge in the center of the board.
Chess board The brain also often makes mistakes about color. The same color can look different on different backgrounds. In the image below, both of the girl's eyes are the same color, but by changing the background, one appears blue.
Illusion with color The next optical illusion is the Cafe Wall Illusion.
Cafe wall Researchers at the University of Bristol discovered this illusion in 1970 thanks to a mosaic wall in a cafe, which is where it gets its name.
The gray lines between the rows of black and white squares appear to be at an angle, but in fact they are parallel to each other. Your brain, confused by the contrasting and closely spaced squares, sees the gray lines as part of a mosaic, above or below the squares. As a result, the illusion of a trapezoid is created.
Scientists suggest that the illusion is created due to the joint action of neural mechanisms different levels: retinal neurons and visual cortex neurons.
The illusion with arrows has a similar mechanism of action: the white lines are actually parallel, although they do not seem so. But here the brain is confused by the contrast of colors.
Illusion with arrows An optical illusion can also be created due to perspective, for example, like the chessboard illusion.
Illusion with perspective Due to the fact that the brain is familiar with the laws of perspective, it seems to you that the distant blue line is longer than the green one in the foreground. In fact they are the same length.
The next type of optical illusion is pictures in which two images can be found.
Bouquet of violets and Napoleon's face In this painting, hidden between the flowers are the faces of Napoleon, his second wife Marie-Louise of Austria and their son. Such images are used to develop attention. Found faces?
Here is another picture with a double image called “My Wife and Mother-in-Law.”
Wife and mother-in-law It was invented by William Ely Hill in 1915 and published in the American satirical magazine Puck.
The brain can also add color to pictures, as in the case of the fox illusion.
Fox illusion If you look at it for a while left side pictures with a fox, and then turn your gaze to the right one, it will turn from white to reddish. Scientists still do not know what causes such illusions.
Here's another illusion with color. Look at the woman's face for 30 seconds and then look at a white wall.
Illusion with a woman's face Unlike the fox illusion, in this case the brain inverts the colors - you see a projection of a face on a white background that acts as a movie screen.
And here visual demonstration how our brain processes visual information. In this incomprehensible mosaic of faces, you can easily recognize Bill and Hillary Clinton.
Bill and Hillary Clinton The brain creates an image from pieces of information received. Without this ability, we would not be able to drive a car or cross the road safely.
The last illusion is two colored cubes. Is the orange cube inside or outside?
Cube illusion Depending on your point of view, the orange cube may be inside the blue cube or floating on the outside. This illusion works due to your perception of depth, and the interpretation of the picture depends on what your brain considers true.
As you can see, despite the fact that our brain copes well with everyday tasks, in order to deceive it, it is enough to break the established pattern, use contrasting colors or the desired perspective.
Do you think this is often the case in real life?
We are accustomed to taking the world around us for granted, so we do not notice how our brain deceives its own masters.
imperfection of our binocular vision, unconscious false judgments, psychological stereotypes and other distortions of worldview serve as the reason for the occurrence of optical illusions. There are a huge number of them, but we tried to collect the most interesting, crazy and incredible of them for you.
Impossible figures
At one time, this genre of graphics received such wide use, which even received its own name - impossibilism. Each of these figures seems quite real on paper, but to exist in physical world it simply can't.Impossible trident
Classical blivet is perhaps the most striking representative of optical patterns from the “impossible figures” category. No matter how you try, you will not be able to determine where the middle prong originates.
Another shining example- impossible Penrose triangle.
It is in the form of a so-called “endless staircase”.
And also “The Impossible Elephant” by Roger Shepard.
Ames room
Issues of optical illusions interested Adelbert Ames Jr. early childhood. After becoming an ophthalmologist, he continued his research into depth perception, which resulted in the famous Ames Room. 
How does the Ames room work?
In a nutshell, the effect of Ames's room can be conveyed as follows: it seems that in the left and right corners of its back wall there are two people - a dwarf and a giant. Of course, this is an optical trick, and in fact these people are of quite normal height. In reality, the room has an elongated trapezoidal shape, but due to false perspective it appears rectangular to us. The left corner is farther away from the visitors’ view than the right, and therefore the person standing there seems so small. 
Movement Illusions
This category of optical tricks is of greatest interest to psychologists. Most of them are based on the subtleties of color combinations, the brightness of objects and their repetition. All these tricks mislead our peripheral vision, as a result of which the perception mechanism gets confused, the retina captures the image intermittently, spasmodically, and the brain activates the areas of the cortex responsible for recognizing movement.floating star
It's hard to believe that this picture is not an animated GIF, but an ordinary optical illusion. The drawing was created by Japanese artist Kaya Nao in 2012. A pronounced illusion of movement is achieved due to the opposite direction of the patterns in the center and along the edges. 
There are quite a few similar illusions of movement, that is, static images that appear to be moving. For example, the famous rotating circle.
Or yellow arrows on a pink background: when stare they seem to sway back and forth.
Caution: This image may cause eye pain or dizziness in people with weak vestibular systems.
Honestly, this is a regular picture, not a GIF! Psychedelic spirals seem to drag you somewhere into a universe full of strangeness and wonder.
Changeling illusions
The most numerous and fun genre of illusion drawings is based on changing the direction of looking at a graphic object. The simplest inverted drawings just need to be rotated 180 or 90 degrees. 
Two classic illusions-shifters: nurse/old woman and beauty/ugly.
A more highly artistic picture with a trick - when turned 90 degrees, the frog turns into a horse.
Other “double illusions” are more subtle.
Girl/old woman
One of the most popular dual images was published in 1915 in the cartoon magazine Puck. The caption to the drawing read: “My wife and mother-in-law.” 
Old people/Mexicans
An elderly couple or Mexicans singing with a guitar? Most people see old people first, and only then their eyebrows turn into sombreros and their eyes into faces. The authorship belongs to the Mexican artist Octavio Ocampo, who created many illusion pictures of a similar nature. 
Lovers/dolphins
Surprisingly, the interpretation of this psychological illusion depends on the person’s age. As a rule, children see dolphins frolicking in the water - their brains, not yet familiar with sexual relationships and their symbols, simply do not isolate two lovers in this composition. Older people, on the contrary, see the couple first, and only then the dolphins. 
The list of such dual pictures can be continued endlessly:
In the picture above, most people see the Indian's face first, and only then look to the left and see the silhouette in the fur coat. The image below is usually interpreted by everyone as a black cat, and only then does a mouse appear in its outline.
A very simple upside-down picture - something like this can be easily done with your own hands.
Illusions of color and contrast
Alas, the human eye is imperfect, and in our assessments of what we see (without noticing it ourselves) we often rely on the color environment and brightness of the background of the object. This leads to some very interesting optical illusions.Gray squares
Optical illusions of colors are one of the most popular types of optical illusion. Yes, squares A and B are painted the same color. 
This trick is possible due to the way our brain works. A shadow without sharp boundaries falls on square B. Thanks to the darker "surrounding" and the smooth shadow gradient, it appears to be significantly lighter than Square A.
Green spiral
There are only three colors in this photo: pink, orange and green. Don't believe me? This is what you get when you replace pink and orange with black. 
Is the dress white and gold or blue and black?
However, illusions based on color perception are not uncommon. Take, for example, the white-gold or black-and-blue dress that conquered the Internet in 2015. What color was this mysterious dress really, and why? different people Did you perceive it differently?The explanation of the dress phenomenon is very simple: as in the case of gray squares, everything depends on the imperfect chromatic adaptation of our visual organs. As you know, the human retina consists of two types of receptors: rods and cones. Rods capture light better, while cones capture color better. Each person has a different ratio of cones to rods, so the determination of the color and shape of an object is slightly different depending on the dominance of one or another type of receptor.
Those who saw the dress in white and gold noticed the brightly lit the background and decided that the dress was in the shade, which means the white color should be darker than usual. If the dress seemed blue-black to you, it means that your eye first of all paid attention to the main color of the dress, which in this photo actually has a blue tint. Then your brain judged that the golden hue was black, lighter due to the sun's rays directed at the dress and Bad quality photo.
In reality the dress was blue with black lace.
Here's another photo that baffled millions of users who couldn't decide whether it was a wall in front of them or a lake.
Illusion is an optical illusion.
Types of optical illusion:
optical illusion based on color perception;
optical illusion based on contrast;
twisting illusions;
optical illusion of depth perception;
optical illusion of size perception;
contour optical illusion;
optical illusion "shifters";
Ames room;
moving optical illusions.
stereo illusions, or, as they are also called: “3d pictures”, stereo pictures.
ILLUSION OF BALL SIZE
Isn't it true that the size of these two balls is different? Is the top ball larger than the bottom?
In fact, this is an optical illusion: these two balls are absolutely equal. You can use a ruler to check. By creating the effect of a receding corridor, the artist managed to deceive our vision: the top ball seems larger to us, because our consciousness perceives it as a more distant object.
ILLUSION OF A. EINSTEIN AND M. MONROE
If you look at the picture from close distance, you see the brilliant physicist A. Einstein.
Now try to move a few meters away, and... miracle, in the picture there is M. Monroe. Here everything seems to have gone without an optical illusion. But how?! No one painted on the mustache, eyes, or hair. It’s just that from afar, vision does not perceive some small details, and puts more emphasis on large details.
The optical effect, which gives the viewer a false impression of the location of the seat, is due to the original design of the chair, invented by the French studio Ibride.
Peripheral vision turns beautiful faces into monsters.
Which direction does the wheel spin?
Stare without blinking at the middle of the image for 20 seconds, and then move your gaze to someone’s face or just a wall.
ILLUSION OF WALL SIDE WITH WINDOW
On which side of the building is the window located? On the left, or maybe on the right?
Once again our vision has been deceived. How did this become possible? Very simple: the upper part of the window is depicted as a window located with right side buildings (we look as if from below), and Bottom part– from the left (we are looking from above). And the middle is perceived by vision as consciousness deems necessary. That's the whole deception.
Illusion of bars
Take a look at these bars. Depending on which end you are looking at, the two pieces of wood will either be next to each other, or one of them will be lying on top of the other.
Cube and two identical cups
Optical illusion created by Chris Westall. There is a cup on the table, next to which there is a cube with a small cup. However, upon closer examination, we can see that in fact the cube is drawn, and the cups are exactly the same size. A similar effect is noticeable only at a certain angle.
Illusion "Cafe Wall"
Take a close look at the image. At first glance, all the lines seem to be curved, but in fact they are parallel. The illusion was discovered by R. Gregory at the Wall Cafe in Bristol. This is where its name came from.
Illusion of the Leaning Tower of Pisa
Above you see two pictures of the Leaning Tower of Pisa. At first glance, the tower on the right appears to lean more than the tower on the left, but in fact both of these pictures are the same. The reason is that visual system treats two images as part of a single scene. Therefore, it seems to us that both photographs are not symmetrical.
ILLUSION OF WAVY LINES
There is no doubt that the lines depicted are wavy.
Remember what the section is called - optical illusion. You're right, these are straight, parallel lines. And it's a twisting illusion.
Ship or arch?
This illusion is a real work of art. The painting was painted by Rob Gonsalves, a Canadian artist, representative of the genre of magical realism. Depending on where you look, you can see either the arch of a long bridge or the sail of a ship.
ILLUSION - GRAFFITI “LADDER”
Now you can relax and not think that there will be another optical illusion. Let's admire the artist's imagination.
This graffiti was made by a miracle artist in the subway to the surprise of all passers-by.
BEZOLDI EFFECT
Look at the picture and say in which part the red lines are brighter and more contrasting. On the right isn't it?
In fact, the red lines in the picture are no different from each other. They are absolutely identical, again an optical illusion. This is the Bezoldi effect, when we perceive the tonality of a color differently depending on its proximity to other colors.
COLOR CHANGE ILLUSION
Does the color of the horizontal gray line change in the rectangle?
The horizontal line in the picture does not change throughout and remains the same gray. I can't believe it, right? This is an optical illusion. To make sure of this, cover the rectangle surrounding it with a sheet of paper.
THE ILLUSION OF A SHINING SUN
This magnificent photograph of the sun was taken by the American space agency NASA. It shows two sunspots pointing directly at the Earth.
Something else is much more interesting. If you look around the edge of the Sun, you will see how it shrinks. This is truly GREAT - no deception, a good illusion!
ZOLNER'S ILLUSION
Do you see that the herringbone lines in the picture are parallel?
I don't see it either. But they are parallel - check with a ruler. My vision was also deceived. This is famous classic illusion Zollner, which has existed since the 19th century. Because of the “needles” on the lines, it seems to us that they are not parallel.
ILLUSION-JESUS CHRIST
Look at the picture for 30 seconds (it may take more), then move your gaze to a light, flat surface, such as a wall.
Before your eyes you saw the image of Jesus Christ, the image is similar to the famous Shroud of Turin. Why does this effect occur? In the human eye there are cells called cones and rods. Cones are responsible for transmitting a color image to the human brain under good illumination, and rods help a person see in the dark and are responsible for transmitting low-definition black-and-white images. When you look at a black and white image of Jesus, the sticks get tired due to long and intense work. When you look away from an image, these tired cells can't cope and can't transmit new information to the brain. Therefore, the image remains before the eyes and disappears when the sticks “come to their senses.”
ILLUSION. THREE SQUARE
Sit closer and look at the picture. Do you see that the sides of all three squares are curved?
I also see curved lines, despite the fact that the sides of all three squares are perfectly straight. When you move some distance away from the monitor, everything falls into place - the square looks perfect. This is because the background causes our brain to perceive lines as curves. This is an optical illusion. When the background merges and we don’t see it clearly, the square appears even.
ILLUSION. BLACK FIGURES
What do you see in the picture?
This is a classic illusion. Taking a quick glance, we see some strange figures. But after looking a little longer we begin to distinguish the word LIFT. Our consciousness is accustomed to seeing black letters on a white background, and continues to perceive this word as well. It is very unexpected for our brain to read white letters on a black background. In addition, most people first look at the center of the picture, and this makes the task even more difficult for the brain, because it is used to reading a word from left to right.
ILLUSION. ILLUSION OF OUCHI
Look at the center of the picture and you will see a “dancing” ball.
This is an iconic optical illusion invented in 1973 by Japanese artist Ouchi and named after him. There are several illusions in this picture. First, the ball appears to move slightly from side to side. Our brain cannot understand that this is a flat image and perceives it as three-dimensional. Another deception of the Ouchi illusion is the impression that we are looking through a round keyhole at a wall. Finally, all the rectangles in the picture are the same size, and they are arranged strictly in rows without apparent displacement.
