Turns out Microsoft Research published a video demo of their grip-sensing pen that we mentioned yesterday. The demo shows how the pen cursor changes in response to different ways of holding the pen, as well as recognizing it as a different type of instrument when held like a saxophone.
The video is posted in Microsoft Silverlight (naturally). If your device is not down with that, it’s also downloadable in mp4 for iDevices and WMV. Tap over to the video web page for these and audio-only downloads.
