From Slashdot today :)
LED's for the forces of good, not evil....
And MIT folk with WAY too much time on their hands...
Geek Alert "Some MIT students built this USB controlled disco dance floor for their dorm lounge. It was built in a week, has 1536 LEDs, 20,000 hand-soldered connections, and is capable of displaying 12-bit color. Check out videos and photos." You can even send the floor an email, though it might not write back.
