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.

Dallenbach Optical Illusion

This is one of those optical Illusions that once you have identified what is in the picture you will always, immediately, see that object. However if you have never seen this image before it may take you quite a while to see what is before your eyes. You may never see it until someone says what it is or points it out.

I originally saw this on Coach Burke's site.
