Draw 3D Images With Beyond Input Pen

The nifty collapsible Beyond pen was developed at the MIT media lab, and is used in conjunction with a head-tracking camera to augment the 3D perspective, which in changes the table display imagery, based on your perspective. the pen itself, is trying to mimic vertical input by turning the collapsing action into a partial virtual pen. The pen itself is tracked with 2 IR markers and a sensor.

This does not quite seem nearly as accurate as the Rhonda 3D drawing method, but new input devices are always a good thing, as we can learn from them.
