This is neat, I've been thinking about building a mechanical version of this since I was child (I used to stare at digital clocks for long periods of time, just to watch the numbers change).
it wouldn't be consistent with the other 'hinges' if it had just one finger, I guess. I could remove it, but I'm trying to be faithful to the original. Nice catch though :) If you notice, no hand goes into the NW and SE position either.
i hadn't thought at look at the orignal - your fingers move differently! i prefer your movement, although i think the original has a slightly more balanced look (fatter fingers). you seem to be using a regular pattern of movement - have you considered choosing which finger to move at random, so that the movement varies more?
[edit obviously i don't mean that the fingers move at random, but since you have two fingers on a hinge you have a choice when it comes to changing how they are arranged]
