Visitors to the Space Child Adventure Grand Odyssey, an animated film showing at the Aichi Expo 2005 in Japan, get a high-resolution digital full-face scan that is edited into the “film” in real time.

Every person who enters the theater gets a role; a Toshiba supercomputer inserts the necessary information and presents the one-time-only film.

Similar technology can be found in John Brunner’s Stand on Zanzibar, Neil Stephenson’s The Diamond Age, and Ray Bradbury’s Fahrenheit 451.
