    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.

a bit of a time leak since there's no enough chars to call x.beginPath(). If someone can figure out how to save enough to do, please do!

Love this interpretation! I'd been thinking of implementing the sequence
