Here is the best optical illusion of 2021

Most of us have encountered an optical illusion before. These bizarre images which titillate our brain to the point where one could believe in magic, a sleight of hand or even an optical effect are in great number on the web. But did you know that optical illusions are considered so interesting that they are the subject of a big competition every year?

The contest in question is called Illusion of The Year and it is held annually by the Neural Correlate Society with the aim of rewarding the best illusions created through ingenuity. According to BoredPanda , in addition to the playful aspect of these illusions, they also help to better understand sensory perception as well as many ophthalmic and neurological diseases.

This year, the competition consisted of three stages: the submission of optical illusions, the selection of 10 finalists and the election of the first three winners. The first place in this competition was won by the Japanese mathematician Kokichi Sugihara and his Shröder stairs.

Schröder's staircase comes first

Do you know the Schröder stairs? It is a 2D staircase created by the German naturalist Heinrich GF Schröder and which has the particularity of taking on the same appearance even when turned upside down.

The challenge that Kokichi Sugihara has taken up is to model this illusion in 3D. Kokichi Sugihara, who currently works at Meiji University, Tokyo, Japan, explained in a description that this image has two interpretations, both 2D and 3D, and it remains a staircase when viewed from above, even if it has been flipped 180 ° on the vertical axis. Take a look for yourself:

This illusion surprised more than one. Some tried to share the illusion with their children while others commented that it took them some time to understand the optical illusion.

When two Coca-Colas seem to be one

If the optical illusion of Kokichi Sugihara won the title of best optical illusion of the year 2020, those of the other two finalists are not left out either. In second place, we find the Briton Matt Pritchard who played with our vision by putting in scene a can of Coca-Cola facing a false mirror in a cardboard wall.

To achieve this illusion, Matt Pritchard took care to place the Coca-Cola and the false mirror in the middle of a table, so that it looks like it is not the other side of the table but the reflection given by the mirror. Then came the turn of Coca-Cola, Pritchard declares the cardboard wall and the fake mirror at the height of the Coca-Cola and, we see another Coca-Cola that is believed to be the reflection of the Coca-Cola in the mirror. . And it's when Pritchard grabs the Coca-Cola to drop his reflection that we see the illusion. As a bonus, the cardboard wall also falls.

As for the third optical illusion, this is a video showing 2.5D curvature grid-shaped digits. This illusion was created by Daniël Maarleveld from the Netherlands with code platform papr.js co-founder Jonathan Puckey. He calls this illusion “ illogical logic ”. The idea is that these numbers are curved in such a way that they appear to be seen from both above and below, to the point where it is also unknown which way the curves are turning.
