    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.

nice!

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.

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.
