High performance Art-Net (https://en.wikipedia.org/wiki/Art-Net) gateway for Adafruit DotStar LED strips (https://learn.adafruit.com/adafruit-dotstar-leds/overview), via a Raspberry Pi (https://www.raspberrypi.org/) running Linux. May work with other LED strips and computers.
In the meantime, see https://github.com/adafruit/Adafruit_DotStar_Pi. The code is based on this library, but optimised for just serving Art-Net.
