LED Painter

The people at Brilldea have come up with LED Painter, a 16-channel RGB LED controller capable of controlling up to 48 independent LEDs. It uses a Texas Instrument TLC5940 to control the LEDs and can be connected to more LED Painter boards, creating a large array of RGB lights. The TLC5940 itself has been modified to make connecting independent LEDs easier.
The team strung together nine of these along with a Propeller-based controller called a Prop Blade and fitted the lights into three windows with semi-opaque glass to create a display of dancing randomized RGB lights. If all the dancing lights have inspired you, the TLC5940s are fairly inexpensive, but you’ll need both through-hole devices and some SMT components to get if off the ground.

You can get samples of the TLC5940 from TI’s website. I picked up a couple tubes of the DIPs myself, not sure if they offer SMT samples, but they’re worth a few bucks a piece otherwise.
