I can see, as I expect many here can, how to write the software to  
drive such a thing given a touch screen and its drivers.  Step away  
from it being a touch screen and consider much the same thing drawn  
with a mouse and it becomes much less mysterious.

But yeah,  I would love one of these to play with.  There used to be  
these screens you could mount on your computer display that would give  
you a touchscreen.  I wonder if they still make those.  In principle  
the same technology could be laid over any surface, calibrated and fed  
into a computer.   The old ones were a bit simplistic in that they  
only tracked one point at a time.  But that is how almost all mouse  
driven GUIs work.
