Optical Illusions Etc...: 13th Man Optical Illusion

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.

13th Man Optical Illusion

Here we have an animated gif file. If you look closely you can count 12 little people. After the gif slides the image around you end up with 13 little people. How does this happen? I saw the same optical illusion done once with solid colored rectangles, the rectangle one is easy to see what happens, but this one is much more difficult because it is people.

If your brain starts to seize up and you must have an answer then click on the picture and it will take you to laurenceholbrook.com where they devote a lot of words and images to making this possible to understand.
