We don't know that this requires much more explanation than the title. A couple of rad dudes from the German-speaking parts of Europe have taken up tools against their old titanium PowerBooks G4s and produced the righteous bit of snow-surfing kit you see above. It was done for a competition asking for creative ways to re-utilize old gear, though judging by all the flopping and crashing that ensued in their tests, this isn't exactly useful. See it on video after the break, and if it really catches your fancy, the PowerBook snowboard can be found on eBay, though no one has been mad enough to bid for it yet.
