In the ten months since we last saw Martin Lihs's WiiSpray application, the Bauhaus University student has turned his combination of Flash programming and custom Wiimote enclosure from a simple tagging simulator to a networked platform for interactive art. We're hoping the next step is "thing that you can buy."
After plugging the Wiimote into the virtual spray can, you can "spray" onto a projected surface, change colors, choose and manipulate stencils, and even save work to a server for further editing at the time and place of the user's choice. Let's see you try that with a wall. Check after the break for a video demonstration!
