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.

I found these images on "Beyond Escher for Real" here they took Escher like impossible images and recreated them with some 3d modeling software. From their page they say,

Herein again, we show that many of the illusions look impossible yet could be realized. This work below presents some of these three-dimensional models that were designed and built using geometric modeling and computer graphics tools.
The following is the "Folded Chess Set" by Sandro Del-Prete. The top image models the original drawing from the original perspective. In the bottom image they take the model they built and rotate it to expose how it could be constructed.
