Hi, this might amuse you (fascinates me for hours I've got one on top of the PC )

Check out the video and if you would like to make your own, follow this link http://www.moillusions.com/2006/03/dragon-illusion.html to find article where I found this which has the paper templates to build you own!

Lol, how does that work?

It portray's an image in your head that it is actually 3d when in reality it's practically flat.

Actually, its because the brain makes assumptions about how the dragon's head is constructed (i.e. convex) when in fact it is concave and even though you know its concave it just won't be convinced otherwise.

As I said, I downloaded the template and made one - so I definitely know it is convex and it still sits there on top of my PC watching my every move.

Don't you just love optical illusions.

Yeah listen to Dave, i'm dumb lmao

i dont understand what happend to dragon... poor dragon
