Best optical illusion yet. Two checkerboard squares look different but are the same shade of grey. (I got a piece of cardboard and cut two holes in it, placed it over the monitor and saw for myself.)
After your brain gets fried puzzling over that picture click on More illusions for a multimedia link by Edward H. Adelson from MIT.
