    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.

Never heard of it :) time for a quote: "Absolute Ignorance is the artificer [...] in order to make a perfect and beautiful machine it is not necessary to know how to make it" - Robert Beverley MacKenzie, 1868 ... gona keep my monkey fingers typing, maybe I will learn something.

Surface. change the values of m and n to modify behaviour, comment cool ones you find

u/taupelink

m=180,n=16 is simple but kind of hypnotic
u/hope4tg

m=(350/C(t)) + S(t), n=(350/C(t)) + C(t) smaller the 350 gets the more intertwined the end shape becomes
