Part #2 of "Tranquility Base Gets Scrooged!" (Part #1 here) and stuff starts getting weird with self-aware holograms (the sci-fi equivalent of "spirits"). Marley's face on the computer screen is my homage to the scene depicting his face in the door knocker.
"And then let any man explain to me, if he can, how it happened that Scrooge, having his key in the lock of the door, saw in the knocker, without its undergoing any intermediate process of change -- not a knocker, but Marley's face."
A Christmas Carol, Stave 1: Marley's Ghost, by Charles Dickens
I'm rather proud of my Marley figure -- there is no recolouring done on him, he's an actual all-grey (bley) minifigure! His transparency is, of course, an effect done in post-production.
There have been lots of adaptations of A Christmas Carol on stage and screen - which version is your favourite? I have a soft spot for the Muppet's version, myself.
Ooh, I've just noticed something: if you use the British short-date format (day/month/year), today is 11/12/13. Cool! You're not going to get three consecutive numbers like that again until the next century (1st Feb 2103). If you use the backwards US format (month/day/year), you're last consecutively numbered date (this century) is next year on 12/13/14 - but your first next century is before ours, on Jan 2nd 2103.
