Flashing LED project?

I have undertaken a sign project for my work that involves LEDs flashing in sequence. We are a Fire and EMS education program and want something that is going to grab attention. At first the project was supposed to be just solid burning lights but has been changed. I'm guessing they want something like the old style movie poster chasing lights or alternating flash between 3 sets of LEDs. It's a little more advanced than I had planned and don't know where to start as far as components go. I've already got the switch they want me to use,  it is very similar to a toggle switch but has a safety cap. My sign is a little larger than a standard letter size paper and I'm thinking 10 or 15 lights across the top should look pretty cool. Any suggestions on where to start or what
I need?

Thanks,

Matt

I found an instructable that should work for your project. The author made it with almost 50 lights, but its attached to a poster board and should work very well for your project. Just adjust the number of LED's to what you need.
