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.

Up the Down Staircase

Here is a real life example of "Schröder's staircase" illusion. This optical illusion is one of the more famous, classic reversible figures. Can you see the stairs right side up and upside down?

Here is the classic version of the illusion.

Schröder's staircase

Looking at the illusion above, if the green wall is closest to you then you will be walking upside down. If the pink wall is closest to you then you are walking upright. Either way you are walking on the same blue treads. Of course if your willing to walk sideways then you can use the black treads.

Took me a while, but yes! I needed to turn my head upside-down, and the illusion popped out.
