Our students used an Andy Mark product (light strip:
AM-2640, complete kit:
AM-2645). I've got a video of the different modes that our team implemented (

AndyMark's LED strip is controlled with SPI -- the controller (Arduino) sends a 3-byte message with an RGB value, and each subsequent message shifts data down the daisy-chain. By updating the entire chain 30+ times per second you can create complex patterns or animations.
