    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.

I like this golfed rendition! :]

i think i like this better than the original :)
u/yonatan

what's the deal with the k^64 tho? seems like it'd spend 64 iterations building the fbm in T and then 64 more doing fillRects??
u/yonatan

k&63 I'd understand...
u/yonatan

oh right, k isn't the loop counter
