equally awesome art project. A student at Bauhaus University in Germany modded a Wii-mote, putting the waggle-happy components in a spraycan for an interactive graffiti project.
According to SlashGear (because we don't speak German), the Wii Spray device allows users to virtually spray-paint walls -- presumably using some kind of sorcery. Neato, but we'd still like Jet Set Wii-dio, please (and we even figured out a name for it!).
