Musical Magic!: Boombox Optical Illusion
Note: Video of the trickery after the jump.
This is an image of a boombox created out of cassette tape that only looks like a boombox when viewed from the proper angle. Otherwise it just looks like a bunch of metallic rat turds strewn across a kitchen floor. That said, I watched the whole minute-long video at least four times, and not just because I'm convinced I caught a gimpse of that girl's underwear when she was getting into position, but I am gonna watch it at least six more times just to makes sure.
Hit it for the trickery in action.
