Chung Lee demonstrates and explains how you can use a WiiRemote for headtracking and how this technique could be used for view dependent 3D effects on your desktop- or TV screen. Awesome!
I will try it out with my own 3D engine as soon as I have a WiiRemote or similar hardware. It should be easy to implement since the whole 3D illusion is based on simple matrix manipulation (projection matrix) of the rendering pipeline. The WiiRemote could be accessed with JInput.
But first I have to write some exams ;)
