    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.

how does this work!?
u/KilledByAPixel

it is a cellular automata, each frame it tires to move the snow down and left or right randomly if the target cell is empty
u/Odog8

oh wow
u/tomxor

Wow nice! it's great how an effect can take on new meaning when finding a different way to frame it.

I was not able to remix because it's a self-destructive code that can run only once.
u/pavel

Use u instead of T to store the data. u does not persist between edits.
u/KilledByAPixel

ah thanks pavel, good call
u/akx

This reminds me of an algorithm I discovered in 2012: https://akx.github.io/spacefill/spacefill.ht…
u/rodrigo.siqueira

It reminds me of the brain's synapse formation process (synaptogenesis) and neural embryogenesis. May be a similar algorithm (but in 3D or in higher dimensions) could be used in the simulation of stochastic neural networks.
