The maths behind the Spirograph toy.

September 11, 2019A year ago, I was introduced to the Spirograph toy when I was looking for a gift I could 3-D print for a friend. (Yes, I’m 20 years late.) Whilst I was realising what was missing from my childhood and wasting tons of paper, I could not stop thinking about the maths behind it. So here is a fun post about the maths behind the Spirograph toy, complete with some sexy curves (SFW) created using my Spirograph web app.
