It's Like Google Docs...but Not

I guess if I were to describe the goals of this this paper computing technology it would appear to be less than a good thing because from what I can tell it has the goal of being a paper-based version of Google Docs. What's up with that? However, once you consider that it is meant for collaborating artists, it makes more sense.

This early stage technology comes from a group at the University of Tokyo and uses a laser, camera, computer and a UV light from an XGA projector to allow users to erase, copy and print hand drawn sketches on paper so that the paper itself becomes interactive. Particularly fascinating is the thermo-sensitive ink which disappears when heated with the laser--that's how you erase! .
