You'll Dance to Anything

There is something interesting at Slashdot about some MIT students who built a "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. You can even send the floor an email, though it might not write back." Later, these same students defeated a bunch of athletes in a Battle of the Bands competition.
