Well of Lights (1992), was developed by Toshio Iwai while artist-in-residence at the San Francisco Exploratorium, Iwai used computer graphics and a video projector to create several hundred animated aquatic creatures that “swim,” play, and change form in an ethereal vivid blue environment that suggests both air and water.
