Thank you!
I took the screenshot with SqueakJS but did not occur that I can share the link this way ^^;
Yeah it's completely undocumented (unless you read the source)
😅

It's fun indeed.
I remember making some Etoys to draw some regular waveforms...

I'm unable to think algebraically very effectively but can think visually (for example I didn't understand the fourier

As a visual person myself, Fourier transform did only really click with me intuitively when I saw it related to epicycles. See Mathologer's video here:

Thank you for that video! Really enjoyable – I knew the epicyclic explanation for how Fourier synthesis can generate a curve, but never understood Fourier analysis, how to find the factors for a given curve. I had a light bulb moment in the last part of the video where all the integrals in the infinite sum become zero except for one particular term. Beautiful!
