I thought the video was sped up for much of it. The person inside the Android suit has had wayyy too much caffeine. (which of course makes it even more fitting on a developer site error page)
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.
I imagine how hard it's to dance inside that stuff.
