The problem is how do I record everything I do on my pc without a video camera?

Set your camera (or friend with a camera) to snap pictures every five(?) minutes.

The guy in the original video seems to have used ScummVM (judging by the final "Thanks" page). That explains a bit of the speed - you can put scummvm in super-fast-mode; also that's why he didn't play Grim Fandango, which is not supported by ScummVM.
