I'll be brutally honest: Not cool. It's old and boring and not in the least difficult. The software is what would've taken a while to make, and even that would theoretically consist of little more that two for loops to scan through each frame of video and output it to the audio jack.
Thinking about it some more, I suppose they wrote a program to manipulate the soundcard output, but I'm still interested in the specifics.
