PBS Arts OffBook has a fascinating short on generative art, a practice composer Luke Dubois describes as surrendering "control over some aspect of what's going down, to a process." For example, he took the day-to-day casualty stream of the Iraq war, and turned it into a six movement string quartet that reflects the "arc of the conflict." OffBook also talks to game designer Will Wright about Spore and Scott Drave about his evolving, connected Electric Sheep screensaver. Don't miss the video below.
