8x8 Arduino powered RGB LED Circuit with PWM

Here's an arduino powering a home made LED driver circuit. The circuit uses 4 shift registers to drive 8x8x3 = 192 individual LEDs using only 3 pins (data,clock,latch) on the arduino. Pulse Width Modulation allows for 16 levels of each color on the board, hard to see in the video but lots of pretty colors are possible, including white. Next project will be to eliminate the dedicated arduino and move to a single atmega16 chip on the board.

Schematic and code is linked to from here:
