If it's not straying too far, I'm pretty sure that it was in an issue of Electron User that I first saw the argument that a circle turned on its side looks like an ellipse, so if you use sin and cos to calculate points on an ellipse and join them with lines, you can do a sort-of rotating polygon. Which sparked pretty much my entire first decade of programming.

Also, it made the centrepiece question on my maths GCSE, about equally-spaced carriages on a Ferris wheel, super easy to solve. That was lucky!
