Looks really nice. A few things that I think might make the presentation a bit clearer:<p>1. Using polar coordinates makes the maths a lot cleaner than using Cartesian coordinates. However you then either need to explain polar coordinates, or you assume people remember polar coordinates from high school which is often not the case in my experience.<p>2. I think the positioning of the points is a little bit opaque. I was expecting to see (r * cos theta, r * sin theta) and it took me by surprise to see an addition in there. Either just noting that stupid computer graphics libraries don't put the origin at the center, or adding that translation later (which is a chance to talk about function composition) might be beneficial.<p>(I've written my own take on this same topic, starting at <a href="http://www.creativescala.org/creative-scala/polygons/" rel="nofollow noreferrer">http://www.creativescala.org/creative-scala/polygons/</a> It will take a little bit more than 5 minutes to get through it :-) It's really fun and you can do a huge amount with parametric curves.)

I like clarity of your examples. You could draw an inspiration from Daniel Shifman's book "Nature of code" (<a href="https://natureofcode.com/book/" rel="nofollow noreferrer">https://natureofcode.com/book/</a>) - see chapters 2 and 3 for instance.
Hey there, OP here.<p>I jotted down some thoughts on how I think about (simple) animations and how to create them with some programming (in Python).
I'd love to hear your thoughts on my write up and also what directions you suggest I take these personal explorations in.
This is very accessible. With a few tiny changes it could run in JS in the browser, in a fiddle or something. Then reader could tweak the code and see changes without having to run pygame.
Drawing a circle by drawing circles - tiny ones, they will just look like single pixels - might be confusing to some, including me. I would suggest connecting adjacent points with lines, that is conceptually not really harder than just drawing the points and it will always give you a complete curve even if a step jumps across a couple of pixels.
