Laser Tag is a new project from Graffiti Research Lab. The idea is that you use a high-powered laser pointer to trace a pattern on the side of a building, a camera captures that pattern, some software processes the capture, and a projector displays the graffiti-ized pattern back onto the side of the building, more or less in real-time. The effect is pretty cool. The process and source code are available here.
