Could the Game of Life run Doom, since it's Turing-complete ? I remember seeing an excerpt of a video where you could run the Goal inside the GoL.

Yes, you'd just need to have a way to provide input (probably easiest as a demo file), and a machine big enough to simulate the pattern. You'd definitely be waiting for a while to see any action, though :P
