Kanizsa Triangle E-mail
(2 votes, average 4.50 out of 5)

An optical illusion, in which the eye perceives a white upright equilateral triangle where none is actually drawn.

Also, the nonexistent white triangle appears to be brighter than the surrounding area, but in fact it has the same brightness as the background.
