it works differently from most touchscreens, uses IR light spectrum to shine through the surface so it can located whatever is on the screen. that's interesting to me. I think if the whole thing were put vertical and walls were made out of them and they could talk to each other and you could have a "personal assistant" follow you around the a building and give you information (i.e. how to fix this blasted toilet) then we'd be talking serious usefulness.
we aren't there yet, though
