Very amazing pictures, we already had them separately, but now the selection is larger and more interesting. Let's look

Impossible triangle made of bones

Unusual photo frame

Impossible design

Impossible Arch

Construction of the impossible cube

Palace of Illusions

Escher, sphere

It has been known for about a hundred years that when an image consisting of light and dark areas appears on the retina of the eye, light from the brightly lit areas seems to flow into the dark areas. This phenomenon is called irradiation.

Illusions of color perception

Gaze followers. Surprisingly, yellow dots appear only in the place where you look. How do they know?

Santa Claus We look at the picture for about 30 seconds, then we look at the wall or a piece of paper. Have you seen Santa Claus in color?

White squares Here you can observe two illusions at once. The illusion of stripes moving relative to each other and deception of shade (gray-white squares have the same color and shade, but look different).

Yellow and even yellower
Look at the animated picture. Squares appear once per second (if animation is disabled in the browser, turn it on, or just click on the picture). Each new square looks more yellow than the previous one. In fact, the color of the squares is identical. They are exactly the same. But the transition of the gradient from yellow to red creates this effect.


Flicker Circles Count the white and black dots on the circles.

Dual green The green background is the same everywhere, although it seems that the color is more saturated in the central square

Disappearance Look for about 1-2 minutes at the point in the center. You should see the colored spots on the square begin to disappear. As a result, you will see a clean square and a dot in the center. The phenomenon is explained by retinal fatigue.

Illusions often lead to completely incorrect quantitative estimates of real geometric quantities. It turns out that you can be wrong by 25 percent or even more if you don’t check your eye estimates with a scale ruler.

Visual distortions

Cube

Parallel lines appear distorted and move.

Different identical wheels. The wheel rims are the same size, although they look different.

Square
The picture shows an absolutely even and regular square, which looks curved due to the color contrast and patterns filling it.


Look at still images and they will move!

Movement Illusions

Gyre

Wavy mesh
Another illusion of a wavy surface. Also, there is the illusion of non-parallelism of parallel segments


Colored worms
Another illusion of Kitaoka - colored worms


Pulsating Star
Shift your gaze a little from one point to another and you will notice the pulsation of the star

Splitting

Hypnotic circles
Viewing this image for a long time may cause nausea and headache.
Respect to Akiosha Kitaoka for such a strong illusion.
