Over the summer, I ordered a batch of WS2812B LED strips. Each pixel has a built in controller that lets you address an arbitrary number of points in full RGB with a single data line. Despite running into some small issues, I finally got it completed last week.
Overall, the display has 690(30x23) individually addressable RGB LEDs being controlled by a single BeagleBone Black. The BBB is running Yona Appletree's fork of the LEDscape library which allows for network control of the display. By sending OPC(open pixel control) commands to the BeagleBone over Wifi, any machine on our network can light up the display!
