    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.

The base code draws a tube. 1/S(i%h+h/2) radius makes the tube have a square cross section.
u/pavel

(Y*Y<8e5||Y%1) randomizes the radius between 0 and 1 near top and bottom.
u/pavel

Err, between -1 and 1, and this makes the top and bottom panels.
u/cantelope

I see some gathering of points in the middle of the top and bottom panels, but other than that, a faithful reproduction. kudos!
u/pavel

I use polar coordinates, even though the radius is uniformly random that results in more dots near the middle :/

I was hoping someone would come up with something better to do with that function. Awesome! :)

FYI the trick of not putting a delimiter between s and l in the hsl call does not work in Safari, its all just black.
