Where is the black hand pointing to?
The same direction as the small (slow) hand on a normal clock.

#23Earlier quoted context omitted.

Not quite, the "0" of the minute hand is always aligned with the direction of the hour hand, so it points >down< at 6:00 unlike an ordinary clock.
The black hour hand is moving the same as a normal clock.
The maroon minute hand is rotating at 390 degrees per hour relative to the clock face. It's rotating at 360 degrees an hour relative to the hand it's mounted on.

#24Nice. Reminds me of one part of the Masagin demo [1], with lots of nested dials synched to the music.

#25Cool.
Why not go one step further and show epicycles for each minute as well.

There is, click the _:00 button, and zoom in to see the blue/teal seconds hand.

#28Newton, Shmooten, Epicycles worked!, they just didn't add enough layers. I'll put this next to my wonderful flat-Earth globe. https://makingmaps.net/2007/09/19/making-flat-earth-globes/

#30about 20 years ago a built a really really janky mechanical version of this.
Super cool, any pictures? I think the minute/second hands would probably be too hard to reliably see, but this would be a really unique looking watch.
lol there might be some on my nokia phone .. just let me dig that out of the closet. To be clear this project was moderately large, if i recall the hour hand (which was the longer in my design) was about 1 foot long.
