as someone who really enjoyed playing with the plastic-and-ink version as a child, this is awesome!
Excellent job! I had a spirograph as a kid and this brought back a lot of memories.
I don't know what I'm doing here but I like it and keep doing it.
Is there any way to drag the inner gear using iOS?
No, I haven't given the mobile experience much love. Hoping to a write a native app soon!
In my calculus class, we wrote down parametric equations defining the curves you get.
In my abstract algebra and number theory classes, I got the students to figure out the rule predicting how many loops the figure will have.
