From Wikipedia: Moondust is a 1983 generative music video game created for the Commodore 64 by virtual reality pioneer, Jaron Lanier. Moondust was programmed in 6502 assembly in 1982, and is widely considered the first art video game. Moondust is also considered to be the first interactive music publication, and it sold quite successfully.
Moondust's gameplay is characterized by graphical complexity, and the game features an abstract ambient score. The goal of the game is to guide a spaceman around the screen creating strange patterns and getting bullet-shaped spaceships to pass through the trails that the spaceman creates. The in-game scoring system assigns point-values according to an algorithm.
