Forget e-paper: if the University of Tokyo's Naemura Lab has its way, we'll interact with the real thing. The division's new research has budding artists draw on photochromic paper with Frixion's heat-sensitive ink, turning the results into something a computer can manipulate. A laser 'erases' the ink to fix mistakes or add effects, and an ultraviolet projector overhead can copy any handiwork, fill in the gaps or print a new creation.
