The communication between two visitors produces a virtual world in two empty rooms. Virtual organisms appear and grow in response to the position, movement and gesture of the visitors, and evolve as the visitors converse with each other. The virtual organisms take in e-mail messages sent from outside via the Internet as genetic codes, thus linking up the visitors with the outside world.
