    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.

I wish there was a way to autolink youtube videos as an audio source for dweets ... behind an automuted UI obviously.

nice! its a lfsr, i have feeling you can do pretty neat patterns with it with correct constant but i didnt have time to mine it out... the 2d mapping part i think could be used for some really cool stuff
