    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.

there's an odd bug in chrome where if hardware acceleration is disabled, or the dweet appears far down the page, the arcs close their paths and create unwelcome diagonal lines. I have a more robust version but it does not fit in 140b.
