    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.

doof: finally got what i originally wanted d/3899 to be -- the lineTo(0,0) takes care of the evenodd artifacts, and the addition of more circles is timed with the contractions. i'll stop with the circles now, i promise. :P
