According to graff news...this university design project, the WiiSpray concept lets you insert a Wii Remote into a spray can-shaped shell. You will then be able to use it as if it were a real spray can on a digital display. To make it even more realistic, colors are changed by physically swapping out different caps so you actually get a feel of the “color” of the object you are holding.
The picture seen here is the latest mockup, a vision of what the final product might look like. It’s not all talk as a prototype has already been made, though this final rendering is closer to what the creators have envisioned it to be.
Though it seems like a very serious project, don’t get your hopes up on seeing it on your Nintendo Wii. It’s not really a commercial effort to get a WiiSpray game published, but rather just making use of the Wii sensor technology together with its own server to promote graffiti art and collaboration. But if it ever does make it as a game, this would be a good one for future graffiti artists to practice their trade. So even if you view it as a public menace, the upside is that kids will have some experience under their belt, and the drawings that are viewed as vandalism will at least be pretty.
