If you remember their last video, these two chaps from the German Research Center for Artificial Intelligence Center demonstrated a hack for the Balance Board enabling them to travel through Google Earth and Second Life with the peripheral. In this video, the two have modified the board to control movement in another virtual world -- World of Warcraft.
The Warcraft portion doesn't appear until the 44-second mark, and you can't really do much with the Balance Board save walk around, so don't expect to take down any high-level elite mobs or lead a raid with the hack. But it's still cool to see non-traditional uses for the expensive peripheral! For more Balance Board mods, stay tune for our own Mike Sylvester's Wii Racing Experiment!
