Fun with LEDs

Tonight's use for old hard drives. From the video's description:
This is a hard drive clock I built from a 3.5" hard drive, some tri-color LEDs and a PIC16F252 microcontroller. It works by shining the LEDs underneath a platter with a slot cut into it, and by timing the various colors it can produce an analog clock display as well as other patterns.
