Something about that dancing robot crossed over in to the uncanny valley for me. The strange part is, I can't tell why. It's not like it looks human in any way.

Something about that dancing robot crossed over in to the uncanny valley for me. The strange part is, I can't tell why. It's not like it looks human in any way. Maybe it's because it appears to move in such an unnatural way. The physics of a short-legged, walking trashcan means it shouldn't move the way it does. Interesting how our brains can make these types of evaluations on such a low level.
