14 LED "knight rider" with hardware PWM

wow :o that was literally the best experience I've ever had with micros. Everything came together flawlessly, there were literally less than three times when I even had to debug anything, and all of those were minor issues. I think only two times actually... BTW there are two red LEDs in the center so you can see where it is.

From the youtube description: An arduino hooked up to two ATtiny2313 microcontrollers for a total of 14 PWM pins, for which I have made a very simple way to assign the values in a 14-character array to their duty cycles. Each LED has 8-bit resolution (256 brightness levels) and can show any pattern you want, at any speed you want.
