It's time to do eye gymnastics, have fun and stretch your imagination! In this collection you will find bright and unpredictable pictures and very curious puzzles for those who like to double-check everything personally. In the same drawing, there may be several plots at once, and some images may seem “alive”. Don't worry, it's completely normal.
25. Is it a vase or human faces?
Here are two different stories in one picture at the same time. Someone sees a bowl or a figurine, and someone sees people looking at each other. It's all about perception and focus. Switching from one scene to another is a good exercise for the eyes.
24. Bring the image first closer to the face, and then back
Photo: Nevit Dilmen
It may seem to you that the ball becomes voluminous and even takes on color. Beware, they say that if you look at this drawing for too long, your head may hurt.
23. Wriggling figures 
Photo: Wikipedia
At first, you may think that the columns and rows of white and green polygons are writhing like a flag or waves. But if you bring a ruler to the screen, you will understand that all the figures are arranged in a strict order and in a straight line, both vertically and horizontally. In the picture, all angles are either 90 degrees or 45. Do not believe your eyes, as they say.
22. Moving circles
Photo: Cmglee
For some, a simple glance is enough to immediately notice the movement, while others will have to wait a bit. But sooner or later, you will definitely feel that the circles in this picture are rotating. In fact, this is an ordinary picture, and not animation at all, but ours can hardly cope with such a set of colors and shapes at the same time, and it is easier for him to decide that something is rotating on the screen.
21. Red lines on a colored background
Photo: Wikipedia
The red lines in the picture appear to be curved, but it's easy to prove otherwise with a simple ruler or even a piece of paper. In fact, such an optical illusion is achieved using an intricate pattern in the background.
20. Black tops or bottoms of the bars
Photo: Wikipedia
Of course, the black edges are the tops of the painted bricks. But wait… No, it's not! Or so? It is not easy to understand, although the picture does not change at all, in contrast to our perception.
19. Optical plug
Photo: Wikipedia
This drawing is a bit like a 23-point picture, only now there is also a giant fork. Although if you look closely, it may turn out that this is something completely different ...
18. Yellow lines
Photo: Wikipedia
Believe it or not, but the image shows 2 absolutely identical yellow lines in length. The deceptive prospect of black stripes can be confusing, but we advise you to take up the ruler again.
17. Spinning circles
Photo: Fibonacci
If you look strictly at the black dot in the center of the picture and do not move your head, the circles around it will begin to rotate. Try it!
16. Moving squiggles
Photo: PublicDomainPictures.net
This psychedelic picture is a real mystery to our brains. Peripheral vision always seems to be moving around the edges. No matter how hard you try, the squiggles will still move somewhere nearby, and not where you look.
15. Gray stripe
Photo: Dodek
Probably, it seems to you that the strip in the center changes its color from one end to the other, as if someone's shadow falls on it. In fact, the center line of one, and the easiest way to check this is with 2 sheets of paper. Cover the top and bottom of the drawing and you'll see what I'm talking about. The only thing that changes in this image is the background color.
14. Black shadows
Photo: Wikipedia
Fascinating picture! It doesn't dazzle or make you sick, so don't stare at the screen for too long.
13. Flowing pattern
Photo: Aaron Fulkerson / flickr
It feels like the wind is blowing over the surface of the field... But no, it's definitely not a GIF. Although it's hard to believe if you look at the image, moving your eyes from one point to another. If you look strictly in the center, the picture should gradually freeze or at least slow down.
12. Triangles and lines 
Photo: Wikipedia
These rows of stuck together triangles appear uneven, as if they are arranged diagonally. In fact, they are still drawn parallel to each other. Is there a line?
11. Cow
Photo: John McCrone
Yes, it's a cow. It is not so easy to see it, and sometimes it takes a little time, but if you look closely, you will definitely see here not only chaotic lines and spots, but also an animal. See?
10. Drowning floor
Photo: markldiaz / flickr
It may seem that in the center of the picture it seems to be sinking or being drawn inward by something. In fact, all the squares of the same size and shape are located evenly and do not float away. The illusion of distortion is created by white dots on the edges of some squares.
9. An old woman or a young girl?
Photo: Wikipedia
And this is a very old, almost classical, optical illusion. Everyone manages to solve the picture in different ways. Someone stubbornly sees a young girl with beautiful cheekbones, while someone is immediately struck by the huge nose of an old woman. But if you try, you can see them both. It turns out?
8. Blackheads
Photo: Wikipedia
This optical illusion gives the impression that small black dots are moving all the time in the picture. When you look at different parts of the drawing, they either appear at the intersection of lines, then disappear. How many dots can you see at the same time? It is very difficult to calculate!
7. Green swirl
Photo: Fiestoforo
If you look at this picture long enough, it may seem that you are being sucked into a vortex! But it's common flat image, not a gif. It's all about the optical illusion and our brain. Again.
6. More spinning circles
Photo: markldiaz / flickr
And here is another absolutely stunning variation of a static image. Due to the complex coloring and shape of the details of the picture, it seems that the circles are rotating, but in fact they are not.
5. Poggendorff illusion
Photo: Fibonacci
Here is a classic optical illusion, named after the German physicist I. K. Poggendorf (Poggendorf). The answer lies in the location of the black line. If you look at the left side of the picture, it seems that the blue line should be a continuation of the black one, but on the right side of the picture you can see that it is the red stripe that completes it.
4. Blue flowers
Photo: Nevit Dilmen
Another optical illusion that will seem like a gif to you. If you stare at this pattern long enough, the flowers will begin to spin.
3. Orbison illusion
Photo: Wikipedia
This is another very old optical illusion, drawn by the American psychologist Orbison back in the 30s of the 20th century. The red diamond in the center is actually a perfect square, but the background blue lines make it look a bit twisted or twisted.
1. Optical illusion Zöllner
Photo: Fibonacci
I gave you another classic example of a geometric illusion in which it seems that long diagonal lines look into different sides. In fact, they are parallel to each other, but short strokes across the lines put our brain in a stupor and create a sense of perspective. Astrophysicist Zöllner drew this illusion back in 1860!
Incredible Facts
The winners of the "Best Illusions of the Year" contest have been announced. It is worth noting that the illusion that won the first place is quite controversial, because all the illusions in this competition are surprising in different ways.
These illusions show how our brain processes information about a particular color, the movement of objects, and much more.
First place was given to an optical illusion called "Triply Ambiguous Object". This illusion was created by mathematician and famous illusionist Kokichi Sugihara from Meiji University, Japan.
Sugihara, who won $3,000, noted that in his illusion, an object can have three completely different interpretations.
Optical illusions (pictures)
Illusion - the winner is presented in the video below.
The illusion is made up of 2D image and a checkbox.
The image is placed on a horizontal surface at a certain angle in such a way that it seems three-dimensional.
Mirrors are mounted on both sides of the object, and a flag is placed right on top of the image to show the direction of gravity.
In fact, the flag enhances the effect of the illusion by tricking the brain into thinking that the object has a distinct 3D structure.
Second place
Second place was given to an optical illusion by David Philips, Priscila Hurd and Christopher Tyler of the University of the West of England, the University of Bristol and City University London. They all received $2,000 as second place prize.
Under the picture in
The illusion begins with the presentation of a drawing that appears to be moving upwards.
Suddenly, with the addition of floating dots in the background, the drawing changes its direction, and now it seems to be moving to the right.
Again, suddenly the pattern changes its shape as dots appear in the background. Instead of an inverted triangle, we now see a strip rotating around its axis.
Strange, but the strip continues to spin around its axis even without a background.
Third place
Prize for third place and a $1,000 award was given to the authors of the optical illusion "A Worm's Eye View", Michael Pickard and Gurpreet Singh of the University of Sunderland.
Under the picture inYou will find a video with an illusion.
The illusion plays with direction and color to fool the brain.
It all comes down to the fact that our brain perceives what is in the foreground.
As the slider moves, the relative brightness of the two colors changes, and depending on which of the drawings we consider as the foreground, we perceive the direction of movement.
Here are other contestants whose illusions are incredibly interesting:

Takahiro Kawabe, a psychophysics researcher from Japan, has created an illusion in which static images of numbers, crabs, and paper hearts move when the background below them flickers.
One dayVfairy tale
This illusion was created by Marco Bertamini and Andrew Irving of the University of Liverpool and the University of Manchester.
Under the picture inYou will find a video with an illusion.
In this illusion, the characters are moving along their trajectory, but because the book is moving up and down, it looks like the characters are also moving up and down.
"How can you learn about the movement of objects? Only by comparing these objects with other objects." scientists explain. "This leads to multiple interpretations of the same movement. In short, all movements are relative."
out of place
Under the picture inYou will find a video with an illusion.
This illusion was created by Stuart Anstis and Patrick Cavanaugh. It includes an object placed next to or over a moving background. As a result, the object appears to change its position and size.
White + gray = red
Under the picture inYou will find a video with an illusion.
This illusion plays with your brain, making you see something that is not there. She was created by Tama Kanematsu and Kova Koida. In it, you see a figure that differs in its color from other figures, and it seems to you that it is red.
However, all the lines of this figure are gray.
Who is chasing who
Created by Yale University researchers, this illusion makes it look like the red dot follows the blue on the map.
In fact, the red dot is standing still, while the blue one is spinning around it. The illusion of chaotic movement of dots is created by a map that moves against the background of dots.
tree in winter
In this illusion, an interesting effect is created thanks to photography. The author of the illusion is Lawrence van Dijk from the University of Utrecht in the Netherlands.
You may think that the photos (or rather their edges) are slanted, but in fact they are all located exactly horizontally and vertically.
sequin illusion
The other finalist, titled "Sequin Illusion", begins by using the popular optical illusion "Hermann Grid", where users see a white grid on a black background. However, in this case the background is yellow.
Figures drawn on a yellow background dotted lines. It may appear that the figures are moving. The authors of the illusion Yi-Tsen Kuo (Yi-Tsen Kuo) and Philip Tseng (Philip Tseng) also experimented with a different background color.
Which illusion did you like the most? Leave your options in the comments.
We are used to taking the world around us for granted, so we do not notice how our brain deceives us. The reasons for such errors lie in the peculiarities of the physiology of vision, and in the psychology of perception.

Pareidolia
There are still creepy illusions - pareidolia.
This is an illusory perception of a real object. Unlike dual images, illusions of depth perception, pictures for pattern recognition, where images are created specifically to provoke the appearance of illusions, pareidolia occurs when perceiving the most ordinary objects. For example, when looking at a pattern of wallpaper or a carpet, cracks and spots on the ceiling, clouds, one can see changeable, fantastic landscapes, faces of people, unusual animals, etc. The basis of such illusory images are the details of the actual drawing. Pareidolia were first described by Kalbaum and Jaspers (Kahlbaum K., 1866; Jaspers K., 1913). Some pareidolic illusions arise from the perception of any well-known images. In this case, they can be observed simultaneously in many people.

And here everyone famous person on Mars (NASA, 1976). This play of light and shadow has given rise to many ufological theories about ancient Martian civilizations. Late images of this region of Mars show no face.
Achromatic contrast
The circles are the same shade of gray.
The color at points A and B is the same: impossible to believe, but photoshop confirms
Look in the center at the black dot - the colored spots should disappear.
See the light gray diagonal stripes?
If you look closely at the dot in the center for several seconds, they will disappear. Look at the dot
After 30 seconds, the gray spot will begin to disappear.
Look without looking up at the cross. Did you see green spots? But there is nothing green here.
Changeling- a type of optical illusion in which the nature of the perceived object depends on the direction of view. One of these illusions is the "duck hare": the image can be interpreted both as an image of a duck and as an image of a hare.

These cars look different in size... but in fact they are exactly the same.
This optical illusion works on a very simple principle - our brain determines the size of an object based on the distance to it. The third car is the furthest away, which is why it looks bigger.
Which of the orange circles is bigger?
In fact, they are exactly the same. The whole point is that when an object is surrounded by large objects, it appears smaller than it actually is.
Look at the yellow dot. Move closer to the screen and the pink circles will start spinning.
Believe it or not, squares A and B in this image are actually the same color.
The thing is that our brain automatically determines the color based on the surrounding shadows. Because square B is in the shadow of the green cylinder, our brain perceives it as a lighter shade of grey.
Without taking your eyes off the image, move closer to the screen and you will see that the light becomes brighter.
All dots in this image are actually white, but some appear black.
An optical illusion is an impression of a visible object or phenomenon that does not correspond to reality, that is optical illusion vision. Some visual illusions have long been scientific explanation others are still a mystery.
Optical illusions: optical illusion
The information collected by our eye is in some way inconsistent with the source. optical illusions can cause severe headaches. Therefore, such things should be treated with caution.
There are three main types of illusions:
1. Literal optical illusions
These optical illusions are considered the simplest. They are characterized by a difference in the image (i.e. the perception of the image) and by the actual tangible objects that make up the picture.
A literal optical illusion makes us see objects or figures that are completely different from those shown in the pictures.
2. Physiological optical illusions
These illusions affect the eyes and brain with overstimulation of a certain type (brightness, color, size, position, tilt, movement).
3. Cognitive optical illusions
These illusions are the result of erroneous image perception by our brain and unconscious inferences.
We continue to collect the coolest optical illusions. be careful: some of them can cause tearing, nausea and disorientation in space.
So, each of the following optical illusions is capable of blowing our brains.
See the three pretty girls?
Now let's flip the image.
Our brain rarely encounters inverted images, so it cannot notice distortions in them.

Visualization of Tusi's lemma
This is not a 3D image
What you see in the picture is not a 3D image, but the American city of Boston, if a giant was looking at it, the distance between the eyes of which would be about 200 meters. It would take an airplane to take this shot, but with 3D glasses on, you can see a tiny city that can fit in the palm of your hand.
Water flows from bottom to top
After watching the video, you will get the feeling that pouring water at the very bottom, water flows upwards under the influence of unknown forces. Written by Maurits Escher. This kind of art even has a name imp-art. The trick lies solely in the play of light and shadows (meaning in specially incorrectly placed shadows), which create such an amazing illusion that water is flowing from the bottom up.
Gray is white. We will prove it to you.
An illusion by Edward Adelson that breaks our brains by showing us that a white square is a gray square and vice versa. Here the illusion lies in the play of light, which for our eyes changes the perception of the subject.
Half glass...
3rd dimension
Movement gives our brain an idea of what an object looks like, what shape it is, and so on. The motion parallax effect makes us believe that a 2D image is a 3D image.
Aftereffect
If you look at a moving contrasting background for a long time, then an aftereffect is created if you look at some object. Check it out - watch the video, and then shift your gaze to any object or just look around your room.
Gene is watching you
The illusion of reverse perspective occurs when you look at a concave object, and expect to see a convex one, and creates a “lifelike effect”, as shown in the video.
