    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.

Random cloud generator

u/joeytwiddle

You can click on the code and hit Space to see more clouds
u/jick

I would love to see a breakdown of how this works.
u/joeytwiddle

It's a fractal using recursion. p draws a square with the given parameters. Then it calls p again twice to draw slightly smaller squares, offset from the parent.
u/joeytwiddle

Like this but more random (and with 2 children instead of ~7): http://neuralyte.org/~joey/hwimirror/hwi.ath…
