    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

I teach 9-year-olds programming and used a tidied up version of this to show them how to figure out how something works. They loved it! Thanks! I've added a bit of gap between the strands to make it easier to understand, and I think it looks good. Like Math.max(180*S(a-1.2),0).
u/rnbw

wow, i would have never thought that my recreational programming would be used for educational purposes. glad i was able to help those kids out on their journeys!
