Duuude...seriously cool. I assume the screamers make noise of some sort, but whatever else they do, they LOOK COOL! I love aluminum and rivets (take a look at my links below). I don't know if it's art, but I like it!

I have a couple of dental lights too. Still in the process of building custom aluminum-and-rivets bracket for them. I was a bit sidetracked by completing a Christmas gift of aluminum and solid rivets.

Is there anywhere I can see more of your aluminum projects?
