Big LCDs and their Arduino pal

Bought these big 6.5″ LEDs from SparkFun, and using these TPIC6B595 shift registers, have it all running via an Arduino, with just 3 wires from the Arduino capable of running as many LEDs as I want. Wiring diagram and sample code coming soon, I want to clean it all up a bit. Grabbed several how-to’s off the internet, then tweaked them and the code so it all made more sense to me. LEDs are powered by a separate 12V power supply, and the Arduino just using USB or a battery.
