This was me for years.

And then I had to write some software that needed to visualise a rotary milking platform which is a circle, divided into segments, with different parts of each segment showing different things at different times.

Oh, and since it's rotary, the circle had to be animated and rotate in sync with the actual milking platform.

Oh and different clients had different numbers of bays in their platforms so I couldn't hardcode anything, it had to dynamically draw the platform, animate it and respond to events like window size change.

Suffice to say I had to drag highschool geometry out from the graveyard of my brain

The smarter kids in your class probably do use them.

There is at least one smbc for everything
