Knight Rider Light Bar

UPDATE (2/17/08): Code is available here.
I’m making a Knight Rider (KITT) Light Bar to celebrate the premier of the new Knight Rider Made-For-TV Movie (tomorrow night on NBC). I’m using an Arduino Diecimila board and 18 LEDs.
Here’s a picture from a few hours ago. The LEDs are now much more aligned and some of the wiring has since been cleaned up, but the photo will give you the general idea.
Materials (so far): FedEx box (temporary; looking for a suitable plastic container) with black construction paper for the housing. Arduino, 18 LEDs (wired to 9 output pins on the arduino – two LEDs in parallel per pin), 9 75 ohm resistors (note, 75 is not the right value, but they were the closest I had). The faceplate is made of cardboard, tissue paper (light diffusion) and some cheap car-window-sun-shade-material I found at Target.
Here’s what it looks like in action (this vid is from the afternoon, before the housing and faceplate were ready): kitt2.mov.
