    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.

The music slowly changes over time and will not stop on its own. This is a new idea combining the oscillator setup with byte beat music to allow for enough space to write graphics code!

Sorry username, I know it is loud and may play automatically in firefox! (even though it shouldn't) I won't be posting any more music for a while so you are safe (for now).
