beautiful! So the numbers describe how many teeth are on the wheels. The "dark moons" are attached to wheel 19. The motion is dictated by one "tooth-movement" of the 47. Is that right?

@douginamug Thanks! And yes: The double moon mask is virtually attached to gear 19; the solar year pointer turns along with gear 47.
