In years of doing this what I do, I have come across various optical illusion patterns whose effect often can’t easily be explained. Still, them patterns provide very intensive results, most often having something to do with illusory movement of some sort. I have also learned how various patterns can cause nausea and make you feel quite uneasy. Just look at today’s illusion for example: not only will the water automatically begin pouring after some time, I bet it won’t take it long before you won’t be able to look at the given pattern no more. It somehow makes my head hurt, yet I can’t rationally explain why is this happening. If you feel masochistic feel free to use this picture for your desktop wallpaper. I dare you to try it :D Let’s see how long does it take before you go berserk!
