A dancing game written in Python, an interpreted programming language. The game was originally written to run in Linux or Unix, but thanks to the beauty of Python and the portability of SDL, it runs on Windows, BeOS, and many other platforms. The toolkit that binds it to SDL is pygame.

Currently the game is loosely based on Dance Dance Revolution, of which theGREENzebra is very addicted to. Soon pyDDR will be pyDance, part of a group of packages called pymani that also includes pyGroove. The other future inclusions will reflect games like ParaParaParadise or BeatMania.
