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.

Table Illusion

I had seen this illusion before but for some reason never really focused on it before. Today I saw it on Coach Burke's site and actually read the info. This exposure caused me to search out some additional info and create this post.

This is Roger Shepard’s “Turning the Tables” illusion. Look at the two tables below. If I told you they had an equal surface area on their table tops, you'd probably say "maybe". But what if I told you that they also were identical in both length and width. Don't believe me? Measure them for yourself. This optical illusion appeared in the Jan. 2003 issue of Discover Magazine.



The below image is given so you can print it out, make a cutout of a tabletop, and reposition it over the other one.

Update: I found this interactive java applet on the Rice University site hosted in their psychology department's space. The applet allows you to really examine this illusion.
