Early computer animated singer by the Kleiser/Walczak Construction Company, in their animated short "Don't Touch Me," 1989. She was created by scanning a clay model, then animated using early motion capture technology ("mocap"). Jeff Kleiser and Diane Walczak called her a "Synthespian."
The Dozo short appears in an early computer animation compilation, Computer Visions (1991).
There had been computer-animated music videos before this, but they were for existing artists. This may well be the first attempt to create a virtual artist.
