    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.

Click on the canvas to move the square. It keeps its velocity when it moves, which leads to some interesting orbits

I was trying to remix a snowflake fractal and found mountains instead.

u/Xen

you almost beat me to my secret project i've been working on for last 2 weeks in silence ;-)
u/rodrigo.siqueira

I want to see your project u/Xen. My wishlist is to use x.drawImage(c,1,0) trick to show infinite horizontal scrolling mountains. I like this style of generative mountains since I saw them for the first time in Moon Lander game, Atari's Vanguard and Moon Patrol.
