Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that "seeing is not believing."

Caution!!!! Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse.

The Moving Fish

First let me state that the spiral is animated and moving by design. The spiral is not an optical illusion. That said let's see how we can transfer the animation from the moving spiral to the fish scene. Focus on the spiral center exclusively for at least 60 seconds, then shift your focus to the fish. It's amazing how the fish actually float in the ocean currents.

Update: I now know that this is Jerry Andrus' Tri-Zonal Space Warper. The original instructions were "Stare at the center of the spiral for about a minute. Then look at the back of your hand.It will appear to be twitching and moving."
