The LPD8806 chip has built in 1.2 MHz high speed 7-bit PWM for each channel, so that it can do 21-bit color per LED.  You can set the color of each LED's red, green and blue. The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. Only 2 digital output pins are required to send data down.
