The optical illusions by Japanese psychology professor Akiyoshi Kitaoka are so freakishly intense that I almost wasn't able to write this after uploading the pictures. The psychedelic patterns in Akiyoshi Kitaoka's artwork give a very strong impression that the images are in motion.
If you are feeling brave, have a look through this gallery of intense optical illusions, but beware, the images are funky enough that Akiyoshi Kitaoka's optical illusions come with a disclaimer.
Implications - Akiyoshi Kitaoka's Illustrations have make some people feel dizzy or even in some circumstances make people feel sick. The best way for you not to feel sick is to avoid looking at Akiyoshi Kitaoka's Illustrations. They are however something outrageous and sometimes being sick is worth it.
