I've decided that I'm going to keep posting videos of Kinect hacks for as long as it takes Microsoft to publish a completely awesome game for their little motorised Eye of Sauron. I appreciate that this may be some time, but I've got a two litre carton of orange juice here. No danger.
Today, you can watch a man wielding a sword made entirely of light. It looks pretty cool, and even makes a sort of warbling noise.
The star of the above video, a Mr. Yankeyan, he says:
"Proof of concept of tracking and rendering a lightsaber in real time using a Kinect hooked up to a PC. Imagine the possibilities.
Best viewed in fullscreen 480p. I track a wooden stick and I overlay the light glow on the computer. Drivers using OpenKinect, image processing, tracking, and rendering using OpenCV. Audio recorded and processed using Audacity and played using libao."
