You can tweet a new colour for the tree to @port57tree.
The tree is driven by two Raspberry Pis, four FadeCandy boards, 2048 RGB LEDs and four 60 amp power supplies. It took about 100 hours to plan and build with another 50 hours spent writing the code.
We also made Tetris run on the Christmas tree but the video latency is too high to play that over the Internet :-)
