    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.

Great! Suggestion for future code: Y=t*60 is 1 character shorter than Y=frame and it also prevents the "while line" on top because frame starts with "1" and t*60 starts with "0"
