I am sorely tempted to make a 2015 Christmas Card demo. Specifically, the Carol of the Burger King, with either a nicely redrawn SQ3 Monolith employee singing it (in subtitles only of course holy shit) or a slightly altered JONES Monolith employee doing the same. I'm partial towards the latter since the screen layout would have plenty space for greetings, it wouldn't look too much like the original video, and it would minimize the amount of graphical effort -- just make it snow on the game board, string some lights...
Then, of course, one would take a Carol of the Bells midi and drop in cue points for the lyrics.
