We've had NES consoles controlled by peculiar pads in the past, one notable example being the Castlevania fan who used a dance mat, but what if you could play a similarly legendary, groundbreaking game without any controllers at all? No, we're not talking about Kinect, we're talking about Super Mario Bros. and this incredible set-up from Waterloo Labs.

Here's the smart guys and girls from Waterloo Labs to explain things in more detail. Warning: contains bearded scientists.
