Paper Clock

Clock made entirely of paper, from the book by James Smith Rudolph. I left the case off the outside to show the internal gears and mechanisms. It will run ok for 10 minutes or so before jamming up, then it needs a nudge or two. Sometimes the gears will slip a tooth making the hands jump ahead several minutes. Time lapse near the end of the video (1:09) was taken 1 frame every 10 seconds.
