Kinect hacker Oliver Kreylos and pals are using a couple of Microsoft Kinect 3D game controllers and custom software to enable 3D holographic video chat. Their setup differs from traditional 3D video in that the participant is captured and mapped in real-time allowing others to view them from any angle in 3D. One fortuitous outcome of this experiment is the ability to clearly identify the line of sight of the other participant. [via PopSci]
