Greg Friedland of San Francisco, CA, wrote in with his 32-square-foot LED matrix.
The lights in the Aurora consist of a grid of 544 RGB LEDs capable of ~16 million colors attached to a 4′ by 8′ wood board. The LEDs are controlled by a microcontroller, which is in turn controlled by a program running on a laptop. The computer is the brain of the system, being responsible for creating the graphics that appear on the wall, and the microcontroller relays the messages to the LEDs. The PC software connects to software running on an iPad, which allows interaction with the moving patterns. Also, the Aurora has a mode where the builtin programs respond to music, bouncing and flashing with the beat, turning it into a VJ of sorts.
