    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.

takes about 2.5 minutes for the motion to loop (assuming 60 fps). Don't stare too long!

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.
