Just a note -- Gosu is already the name of a neat little C/Ruby graphics library that wraps up sound and graphics programming in a tiny little package that mostly gets out of your way.

(I believe it was intended for people making little games -- I've used it a few times on my own projects and it's very uncluttered, minimal etc; I used it and Chipmunk to make myself a screensaver of all of my photos falling, bouncing off of each other etc).
