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.

Ferris Wheel Optical Illusion

I love this little animated Ferris wheel.

Look at the red outside edge, is the wheel going around clockwise or counter clockwise?

Are you sure?

Now look at the purple center of the Ferris wheel.

What is the truth of this illusion?

By now you hopefully have realized that this is just a two frame animated GIF and it alternates back and forth between only two positions. It doesn't go around in either direction. This is clearly seen when you focus on the center but look just to the outside edge and it appears that this Ferris wheel makes complete trips covering the full 360 degrees.
