Frets On Fire

Once in a while I read something about Guitar Hero, in the lines of "this is so cool!" and "I wish I could do this or that with it"... So I assume that most people don't know about Frets On Fire: an Open Source clone of Guitar Hero, made in Python, and available for Linux, Mac OS or Windows. Since it is Open Source, you can do with it all those things you wanted to in Guitar Hero. Enjoy!
