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.

Spirals or Circles Optical Illusion?

Spirals or concentric circles? Look at the figures below, What do you see? Are both of these images of spirals plummeting toward the center or does one of these images have only concentric circles?

The truth here is that both images are of concentric circles. The top image is very hard to believe and many of you will mark up your screen with finger prints trying to trace the circles. Here is a little hint, trace the circles on the top image in a clockwise direction otherwise you could go crazy and swear that I'm lying to you.

Well, the circles in the top aren't really concentric, since the center of the smaller circles is higher than the center of the larger circles, but they are all definitely circular
