Less than a month since Kinect’s launch, people are already experimenting with a hacked driver of the Kinect sensor. These include capturing 3d video, 3d object recognition and interactive puppeting. At the moment I haven’t seen full 3d video capturing, and I regard those online experiments as 2.5D as they are only getting the side facing the sensor. But any moment now someone’s gonna link an array of them together to get nearly-full 3d video. That would be awesome.
