    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.

Nostalgiac for me :D I think I chose +t*60 to get rid of the juddering. That doesn't help with sin here, but I think the actual reason for judder is from round-up aliasing on the left side of i/w+f^f, so pre-flooring f seems to mostly eliminate it e.g 999*S(t*.05)|0

Great idea, should be combined with cuts to shaky hand-written black signs with white lettering saying "Clear the canvas!" and "Draw fifty-by-two-hundred rectangles"
