"A group called Waterloo Labs rigged up a few accelerometers to a large wall and projected a first-person shooter onto it. Using some math, they can triangulate the position of impacts on the wall, so naturally they found someone with a gun and bought a large case of ammunition. Even cooler, this group usually posts a 'how we did it' video a few weeks after a project's debut, including source code."
