New optical illusion brought from the mind
Netizens praised the new optical illusion created by a psychology Professor from Japan, Akiyoshi Kitaoka (Kitaoka Akiyoshi). The video is available on his Twitter page.
The frame is a piece of paper. It depicts a black gradient that changes color from dark to light. Kitaoka was also put on a small sheet of grey paper, and began to move it left and right from the center. The audience had the impression that the paper completely changes the tone depending on its location.
