    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.

u/taupelink

I really just kind of stumbled on this effect. I started out trying to animate d/24361, but then I forgot to clear the screen with each loop execution, and I noticed shadows forming...
u/taupelink

...and it turns out there's something about the way that X=1+S(m),Y=S(m*m--) do NOT function as pseudo-random formulas in this dweet. If you replace the X formula with X=2*Math.random() you just get noise....
u/taupelink

Maybe what's happening is that locally, the width and height formulas act like piecewise-continuous trigonometric functions. Hence the curvy-yet-segmented little shapes.
