Third set of optical illusion pictures

Here is another set of small optical illusion and visual perception related images you can link to from your own website / profile page.

Pic #20 of 25(back to thumbnails)

A variant of Edward Adelsons chequerboard illusion: the arrowed squares, a pale one in shadow and a dark one outside the shadow, are identical shades of grey, but that?s not how they look



In case you missed them you can still see the second perception pictures as well as the first set of illusion pictures.
