10th place. Ambiguous Cardboard

Arrows Matt Pritchard, United Kingdom



You can cut out your own cardboard signs that are not clear in which direction they point.

9th place. The chunder thunder illusion

No pixel is moving in the picture.

8th place. Magic Tic-Tac-Toe

Lateral inhibition or how to feel color blind without noticing that the colors of the squares are different.

7th place. 3D Graffiti

Jack Bowers, USA



Upgraded version of the Necker Cube. At first the figure seems impossible, and then the essence becomes clear.

6th place. Helix Rotation

A rthur G. Shapiro, American University. USA



Spiral rotation. The image consists of two columns of dots that move forward and backward horizontally.



What to do: Put a dark filter on one eye and keep both eyes open.



What will be seen:

1. the points look like three-dimensional spirals.
2. when the dark filter is at the left eye, the spiral rotates clockwise; when the filter is at the right eye, the spiral rotates counterclockwise.
3. when the viewer does not use a filter, but blurs the image by squinting both eyes or using a defocusing lens, movement is upward for one spiral and downward for the other.

5th place. Facing-Right Illusion

Kokichi Sugihara, Meiji University. Japan



The bird that always looks to the right. No matter how we twist the bird, we cannot make it look to the left.

4th place. Bodiject Fingers

Kenri Kodaka, Naoya City University. Japan



"Deflated fingers". Feel your fingers as separate entities. If you look at the fingers stuck under the mirror, then the brain will become twisted: it sees the fingers as separated from the body, but feels like its own.

3rd place. Rotating Circles Illusion

Ryan EB Mruczek and Gideon Paul Caplovitz, College of the Holy Cross and University of Nevada Reno. USA The



circle in the center always moves around the circle. Moving 4 large circles are misleading. It doesn't matter that you move correctly all the time, your environment can change the perception of reality.

2nd place. Change the color

Haruaki Fukuda, University of Tokyo, Japan



There are two options. The first option is that the points move from top to bottom, then these are green and red points. The second option is that the dots move from left to right - then the dots turn yellow.

1 place. Dual axis illusion

Frank Force, USA



Around which axis does the rotation take place? Around vertical or around horizontal?
