Optical Illusions Etc...: Concentric Circles

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.

Below are two perfectly concentric circles. One floating perfectly centered in the other. I hear a murmur of disbelief.... Print it out and measure it for yourself.

"Kitaoka Strange Appearance"

I think this may have been created by Akiyoshi Kitaoka.
