Yes Andy,
Exactly what I couldn't find for a while, I knew I had already seen your clock somewhere, I kept googeling to find it back, and couldn't remember it was from someone here !
Thanks for giving me the link again, it's exactly that, I love your old looking, but fool of techno, and but full of mischief ;-)
I have exactly the same stepper as yours, and so far, I feel they are quite slow, so I guess the hands are not dirctly on the shaft of the stepper, and how do you manage to drive the two hands that are on the same axis ?

Edit, I just saw the video, I saw how you did it, but where did you find the necessary gears ?

There is another one, which you probably already know about, it's a big wooden spiral, with a ball rolling always in the bottom position, this one could be nice to do as well.

Thanks !
Christophe
