    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.

saving more space if you only use the numbers: ".012578"

u/corruptio

instead of 7/32, 7

/6.4 and 9/6.4 give interesting digits too

How does this work?
u/yonatan

SVG perlin noise displaced by itself and used as a filter on the canvas. Time controls the displacement filter'r scale.
u/yonatan

the filltext() is required for the thing to paint itself apparently (fillRect works too)
u/yonatan

I half-guessing so if anyone has a better explanation...
u/yonatan

placing the displacement filter as a child of the turbulence node seems to feed the parent's output into both of the child's input nodes.
u/yonatan

oops, not child, sibling.
u/yonatan

tl;dr: no idea :)
