Take each one of the planets, and assign a note to each of them. Then have them orbit the sun. Every time they repeat the orbit, play their unique note. That makes for some interesting music that sounds very similar to a music box. It takes a long time for Pluto to make it all the way around, so you can speed up the tempo a bit. Luke Twyman designed this Adobe Flash program, and you can find it at his website.
A simple ambient musicbox, with sounds generated using the orbital frequencies of our solar system.
