If you have quicktime you should be able to listen to this audio clip. Discovered on my camera this weekend and recorded sometime back in June it appears to be a goose and frog orchestra at the beaver pond down the road. Then again, maybe not, I don't remember recording it. Kind of a cool ambience.
You could convert that track to MIDI and do some interesting variations...or maybe import into GarageBand?
You got it:
