There have been a few video games featuring graffiti before (see: "Jet Grind Radio," "Marc Ecko's Getting Up"), but not like this.

German college students Martin Lihs and Frank Matus have crafted a prototype of a Wii controller in the form of a spraycan.

The resulting Wii mod, called "WiiSpray," recently won a design award from Germany's International Forum Design for its product interface. Hopefully, we'll see game publishers getting on this soon so we have a reason to dust off our Wiis. You can imagine the possibilities and check out how WiiSpray works after the jump. [Via Kotaku]
