169 Best Illusions—A Sampling (SciAm)

Our brains are exquisitely tuned to perceive, recognize and remember faces. In the Illusion of Sex, by Gettysburg College psychologist Richard Russell, the left face is perceived as female while the right face is perceived as male. But the two images are actually identical, except that the contrast between the eyes and mouth and the rest of the face is higher for the face on the left. This illusion shows that contrast is an important cue for determining the sex of a face. It may also explain why cosmetics make women look more feminine.

this is really awesome.

it also makes me wonder how it feels to be the model for that photo
