Wanna start rocking out on your Mac? Maybe you're looking to melt your housemates' faces with a few solos? Thanks to Frets on Fire, you can do exactly that.

Frets on Fire is an Open Source cross-platform clone of the hit PS2 game Guitar Hero. It includes support for OS X, and while the program was originally designed to be played with a keyboard, you can use the actual Guitar Hero controller (along with a PS2 to USB adapter that you can probably grab at any Radio Shack outlet) to play Frets on Fire on your Mac.

Frets on Fire runs fine on Intel-based Macs.
