Face Of The Day: "

From a series on facial illusions:

The Illusion of Sex, by Harvard psychologist Richard Russell, won Third Prize at the 2009 Best Visual Illusion of the Year Contest.
The two side-by-side faces are perceived as male (right) and female
(left). However, both of them are versions of the same androgynous
face. The two images are exactly identical, except that the contrast
between the eyes and mouth and the rest of the face is higher for the
face on the left than for the face on the right.

Nine more here. So who turns you on, the man or the woman? And how much rests on that difference?
