    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.

Now that I’ve accepted that this will probably never fit in 140 chars uncompressed, I might consider working on smoothing the transition when the strong wind starts and stops…

didn’t even use π, so now 81 -> c.width|=0;x.lineWidth=30;x.arc(960,540,200,t*8+S(5*t),t*8+S(5*t+2)+2);x.stroke()

in the future when you do need to use it a nice and short approximation is 22/7 :)
