The 'WiiSpray' Project is perhaps the most badass adaptation of the Nintendo Wii and its Wiimote I've seen (today). The WiiSpray Project was created by students Martin Lihs and Frank Matuse, who regard the innovation as an addition to--not a replacement of--the world of street art, another place to paint.
The WiiSpray Project uses a spray paint can, into which the Wiimote is nestled. According to Lihs and Matuse, the mechanics and feel of the traditional spray paint can are preserved. The projects are saved onto a server, where they can be saved, worked on or deleted at any time.
