This - the illusion of a famous Japanese master Akioshi Kitaoka.
The fact that he is part-time psychiatrist.
So, rested balanced people do not see movement!
Akioshi said that it is necessary to properly relax. I will not give up! Friday after all!
By the way, if the pictures are moving very quickly, then you have time in a psychiatric hospital. This effect is observed in maniacs.
