How do I use this LED strip?
It looks similar to this LED strip: http://www.adafruit.com/products/1138

According to the code linked from that page, it's controlled by a weird protocol used by the Worldsemi WS2811 LED driver chips on the strip: 24 bits for each RGB LED, 800 or 400 kHz data rate, 50 microsecond pause to latch the data. There is a pulse for each bit, 0 bits are a short pulse, and 1 bits are a long pulse.
