    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.

Kudos for the write-up. I like that I can see the result of the code in each revision
u/BirdsTweetCodersDweet

Yeah, these write-up tutorials showing the step-by-step changes in the code are amazing... Thanks!

P.S I wouldn't say it "devolved" into a demo - demos are good!
