Ambient Environments: WindowsXP from Phillip Stearns on Vimeo.
Using only a few lines of code, the default background for WindowsXP is scanned from left to right, using a strip one pixel wide. Each strip is repeated across the width of a single frame. The frames are then animated in sequence at 15 per second. The sound is produced by stretching the barely 5 second startup sound to the full length of the video (x28 times).
