I love that Dragon illusion, it's so cleverThanks "Halloween sucks..."!
I love this stuff! Years ago I used to make papercraft cars that I found on the web. My son always loved seeing what the paper would turn in to. I'm sure to try some of these!
The "moving skulpture" remins me of the dragon found here:
Grand Illusions - Optical Illusions - Dragon Illusion
There are blue and red versions of it available on the web as well.
It's the same idea as used for the "following faces" illusion at Haunted Mansion.
