I just finished writing an article about my Polyathlon entrant, Bot-Choy.  Its not easy to compress a 6 month project into a few paragraphs and photos, but it was a great project and I learned a lot about Infrared Light, talking between Arduinos over I2C, Polarized Light, and much more.

While there is no shortage of DIY aquarium lights out there, hopefully my take on it will inspire others to push the limits to create ever more stunning visual displays.  With 6 sets of RGB LEDs and independent control of all 18 channels, its a light show right in our living room.
