Homebrew Kinect software just passed the "cool" threshold into "a little scary," making Microsoft's camera device do things we shouldn't reasonably expect out of controllers. We couldn't use our Turbo Touch 360s to generate a 3D model of a stretch of road, complete with buildings and scenery, after all. Not that we ever tried.
Martin Szarski strapped a Kinect sensor to his car, hooked it up to a laptop and Nexus One phone (for location data) and set about creating a "point cloud" of his car's path. Using a phone with a gyroscope to better sense the car's movement, Szarski said, the cloud would appear clearer. But for a 3D space captured by a $150 game controller, it's pretty impressive, no? Imagine this cheap DIY tech in the hands of indie devs, who could create levels by exploring in real life.
