From part 41 of Vagabond (http://vagabond.s5.com) this is Shura's Clock that hangs in the temple of the muse-god Zithal in Moon's Rest Mountain. Each of the ten gems stands for each of the ten dwarven gods. (a tenth would be about an hour and 12 minutes.) I know the gears don't actually do anything, but it was only the effect I was going for, not accuracy. I created the shapes in Freehand and rendered the color in Photoshop. Thanks to Stephanie Lostimolo for her gems tutorial!
