I'm way behind in all of my podcast listening, but I'm trying to catch up. I just listened to this episode, and I was blown away.  First at how creative you are, and also at how accurately you were able to describe everything that you did. I have the world's worst visual imagination, but I was able to picture everything that you described. I'm very impressed that you were not intimidated by the programming of the Arduino, because I would have been. I thoroughly enjoyed what you said when you went off script as well. Bravo to you.

My only criticism is that I think your breakers are too big. if you ever drew 20 Amps of power through either circuit you would burn up your 14Gauge bus. You may wish to add fuses to your box or replace the 20 Amp breakers with 10 Amp breakers.

When you get to the point of being able to choreograph your lights to music plase, please, PLEASE do the HPR song (or at least The Free Software Song). 

Thank you for a great episode. It's going on my all-time favorites list.
