Well, as usual I've taken things further than they needed to go...but first, let me explain.
I love the Doomsday Device scenario. It's the most hectic, frenzied race against time in SA, in my opinion, and it's also the most fun. But I was sick of using a crappy prop and a D10 next to it in order to track the countdown, and since I was out of casting material to use with my Hirst Arts Sci-Fi molds and I didn't want to spend money on a pre-made toy....
I made a machine, of sorts. Not sure how it works, but in involves mixing the contents of a green egg (perhaps the one of Dr. Seuss fame) with some grape jam via a computer console. The scale is a bit large, too, as if it wasn't actually built for a human sized model....
...but there's more. Since anything that isn't part of the scenery on the table is an affront to the awesomeness of the scenery, the die couldn't be integrated. And I hate writing crap on a scrap of paper, so....
....I put a wheel on the doomsday device to track its progress toward unleashing Cthulhu. It has 11 positions (D6+3, and an extra 1 in case I houserule something and the "DOOM" station.) and rides on a bearing so the sculpture doesn't wear over time.

This is unassembled, and before I dip-coated it in lacquer to keep it pretty much indestructable.

This is assembled, after lacquer but before dullkote. Note the crate 'o people in the background. I didn't want to spend 20$ on one, so I made it out of some sculpey, a few bits of cardstock painted black, and some spare arms and legs from some Heroscape figures, painted fleshtone. It's not done completely, but it's very close.
