OPTICAL ILLUSION.....2

OKAY you smart peops out there, here's one for you . . .
If you look at the above images from your seat in
front of the computer, the angry face is on the left, and the calm one is
on the right.


Get up from your seat, and move back 12 feet, and VOILA !!...

they switch places!!


(If you haven't got enough room to move that far back, get as far back as possible and then squint your eyes until they are thin slits ....it should work too)

It is said this illusion was created by Phillippe G.Schyns and Aude Oliva of the University of Glasgow

Does this mean that we sometimes may not be seeing what's actually
there?
