That's pretty cool! What does the hardware look like?

Oh, is that a GPS/compass shield? I have to get one of those.

Yeah it's a GPS module, it reports an "angle" and I guess it calculates that by comparing the previous position to the current one. Not very accurate while standing still but works pretty well while on the move.
