A few years ago some students built a D&D prototype for the MS Surface Table computer that looked pretty awesome: http://vimeo.com/surfacescapes

The use of actual figurines with fiducial markers to control the UI was particularly interesting.

This is excellent, thanks for sharing. Do you know of any similar developments for smaller tablets?

Unfortunately, no, I don't.
