I'm a sucker for optical illusions, but sick of the same tired old chestnuts being rehacked, this one was a new one on me though..

Zoom in and out with your favourite picture viewer if you can't get far enough back from the screen. Printing it out at about double passport size (per face) works well too.

Becareful of the rest of this site though- CUPS lurking (I need those Non Transitive dice!)

ah, i've seen that one on the ian rowland site too...nice site though...

i really like the talking tape and those chinese mirrors...you could get a good couple of bizarre presentations out of those...hmm...

Here's another site with a lot of optical illusions and other stuff
