Tech-savvy iPod users with Linux skills have hacked into Apple's music player to make the device play Doom on colour-screened versions of the machine.

Engadget reports project-workers on the iPod Linux scheme have figured out that while the iPod isn't doomed, it makes a worthwhile portable player for the game called Doom.

The software will only work on iPods with a colour screen, such as an iPod photo or present-generation iPod. The software also requires that software to run Linux on the Apple product called Podzilla be installed.

The iPod's existing scroll wheel works as controls for the game, which is not yet feature-complete.
