    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.

a sort of rough #recursive #plasma #fractal

u/joeytwiddle

Ideally we would keep the edges smooth, by holding an intensity for each corner instead of the entire square
u/joeytwiddle

W=width, H=half width, I=intensity, p=plot/plasma/partition
u/joeytwiddle

p calls p four times for each sub-square, with a randomly smaller I
