    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 little golf and a color tweak to get some room to play with performance. it seems like the limit is just in drawing; Math.random() seemingly can't be improved on. I'd like to look at putImageData as suggested by https://stackoverflow.com/a/4901604 because it's possible that color parsing is a big overhead cost.
