I put some Doom in your Doom so you can Doom while you Doom

I'm a sucker for the self-similar pleasures of recursion, so it was with great delight that I learned someone has put a playable version of Doom… inside Doom.

In a video posted by TheZombieKiller, you can see everyone's favorite space marine approach what looks like an arcade cabinet, and then start playing the very game he is inside. It's part of a larger effort to put a number of playable "arcade games" inside Doom; a semi-complete version of Wolfenstein 3D is also available.

Somewhere, Xzibit is smiling down upon us all.
