Hey Kyle

Sounds like a really cool project.

Are you sure you need any special hardware at all? You could use the
PWM out from the arduino and a transistor for each set of LEDs you
want to control then build an array. A friend just showed me this
ridiculously cool site: http://led.linear1.org/led.wiz

I'm talking like I've done this before, but really I'm only part way
through a similar process, so maybe it's all totally wrong:) Anyway,
hope it helps.
