Further proof that if something has a CPU and a screen, someone's rigged it to play Doom...

The code that runs Redbox DVD rental machines has been dumped online, and, in the wake of the company’s bankruptcy, a community of tinkerers and reverse engineers are probing the operating system to learn how it works. Naturally, one of the first things people did was make one of the machines run Doom.
