It's well known that some developers are already working on games for the Xbox 360's Project Natal, and thus have prototypes of the motion sensing device. While the prototype devices may be mechanically quite complete, it looks like the case is far from it.
An image of one of the prototypes surfaced on the Seattle Times website, and it's safe to say it looks like some sort of creepy space robot. It'd be bad enough manning up to dance like a goof in front of Natal, let alone this freaky thing, not to mention working on a game all day with it sitting on my desk, glaring at me with it's beady-eyed sensors. See for yourself below.
