Basic Stamp - Cylon LED project

I've always been facinated by shiny blinking lights.
(Blue ones especially...)
I decided to re-create the famous 'Cylon" light pattern.
(think Knight Rider's KITT front lights going back and forth)

Once again, I'm going to use the Basic Stamp since it's so easy.
Here's the layout:
Pins 0 - 12 are connected to blue LED's
Pin 15 is connected to a pezio speaker for the cool sound effect
Line 14 is my ground bus that has a single resistor going to ground

Here's the video:
