Gosu

Gosu is a multimedia C++ library with Ruby bindings. It works on OS X, Windows and Linux. It was written by Julian Raschke.

The library is licensed under the MIT license, however on Windows and OS X it uses the proprietary FMOD library. The Linux version can use SDL_mixer though, and as such developers can build completely Free games with it.

It is one of only two game development libraries used in the first two RubyWeekend contests.
