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.

San Francisco Quake Optical Illusion

I lived in San Francisco area from 1983-87 and have many fond memories. I learned to drive a manual shift automobile, I met my wife, and I got married. My wife and I spent many a weekend in the city enjoying what this great city had to offer. While living in the Bay area we only experienced a minor quake or two, barely a rumble.

But on October 17th 1989 a magnitude 7.1 earthquake struck the Bay area just before the third game of the World Series at Candlestick Park. This was the worst earthquake since 1906, many buildings collapsed and many others shifted off of their foundations. This picture was taken after the quake.

How is it that this building is leaning so far over yet there is no apparent damage?

Your very sweet not to expose the obvious too early.


Bravo your absolutely correct. I live for the verbal illusion, the setup that might get people to hesitate for 10 or 15 seconds before realizing and accepting the truth.

It is a shame there were trees in the background, without which the illusion would have been even more convincing.
