Ok, I was gonna keep it secret until it was done, but here's what I'm doing...
I decorate my car with christmas lights every year. I have a loudspeaker on the roof playing christmas music. Here are a couple pics from last year:

Here's what I want to do. It won't be this complex, as I only have so many sections of lights on the car, probably only 4 or 5 separate triggers. I want to sync the lights with the music, so I'm thinking of having the music, and the timer start at the same time. I'll program which relays need to close at which times so that the lights work to the music.
And yes it's illegal to have lights all over the car, but I've been doing this for about 6 years and I've only been pulled over once, and all the cop wanted was to shake my hand for a job well done. Usually I just get a siren blip, and they give me a thumbs up when I look. The blinking to the music will be pushing it, so I'll only use that when I'm parked.
