This innovative prototype by Francesco Sommacal is called the 360. While it resembles a snowboard not at all, the basic concept of steering by shifting your weight makes the analogy work. Beyond that, it is not a board, it has wheels, and you would probably not fare well on the snow when riding it. This piece won a Volvo Sports Design Award and the Red Dot: Luminary Design Award. I don't know what those are, but awards are good, right?
The vids after the jump are pretty sick.
