Asd we're on optical illusions I'll post one of my faves (well i'll attempt to as i can't find the damned testing board, therefore apologies in case it goes tits up).
I found this on a website whilstr searching for optical illusions (wanted a good one for my MSN 6 aviator) and would have linked the site to everyone but can't find the one i was at, all i get now are ones that are full of popups so not linking that.
ANyway here goes
