Remember the iconic HAL 9000 computer from the film 2001: A Space Odyssey? We all wanted our own HAL, even though he pretty thoroughly crashed in the movie: "Open the pod bay doors, HAL."
The folks at the HAL Project have been involved with simulating the look of HAL for years. Their first project was an animated desktop back in 1999. The screensaver version of the HAL GUI has been around for years, but it's recently had a major update to provide smooth animation and really authentic simulations of the HAL screens.
