Dragon Illusion

After reading about this on Micah Cowan’s site, I had to build one. You can download a pdf cutout with instructions. Once you assemble it, you stand about 2 feet away and cover one eye. Then move your head around, side-to-side, up-and-down. It will appear as if the entire dragon’s head is moving to follow you. It’s a pretty convincing illusion.
