(As seen on TechRepublic Blog: Put your color printer to good use with this super-cool optical illusion)
Ok, this illusion is pretty darned cool. Basically, you print out this PDF and construct a paper sculpture of a dragon. It makes use of an inverted face illusion, so that if you close one eye while looking at it, it will look like it’s head is moving around to follow you. This video shows how strong the effect is.

I just printed out one myself, assembled it, and set it on the middle of the table in my lab’s common area. I wonder how my labmates will react when they see this tomorrow morning…

I just set one of these up in my cube today, it really freaked out this one girl. Pretty neat.

4 days later…. This thing is a real hit at the office. I haven’t really told anyone about it (just 1 person), now every other person seems to know about it.
The effect is definately pretty strong.

Mertikie, have you tried looking at it with just one eye open? That sometimes helps.

if yours doesnt seem to work get about ten feet away and slowly rock side to side until you see it if that doesnt work get about 3 feet away and close one eye watch until you see it if you still dont make sure the face is pointing outwards if it still dosnt work… look it up!your eyes have been trained with depth persition if you cover one eye there is no 3d image because there is no depth but we have been trained so if an object is smaller we think its farther away . thats how this works!meow! =^.^=
