This is great, also the various calculators and parts designer. I've been looking to build an articulated clock, which is pretty much an orrery like this but without planets and different gear ratios. Difficulty is that I'd like to have the second hand keep straight from minute hand at whole minutes. And I think I need a gear ratio of 61 for that. Or Keep it straight up at whole minutes, which needs a gear ratio of 59 IIRC. Both primes, so not easily achievable with gears. It's been a while since I spent time on this though. EDIT: I could add/subtract 1 rotation via a differential gear I think.
