QQQ is a piece of art made by modding copies of Quake III. The artist, Nullpointer, has modded the Quake III engine so that it renders out crazy, haunting, beautiful high-speed graphics instead of levels. Sometimes he gets people to play public games of Q3 on an Internet-connected server and renders out their movements in the QQQ engine at his gallery installations. The videos are just wild.
