    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 know it’s not that sophisticated, but it’s my first attempt at a dweet. I’m learning a lot looking at all the amazing work here.

u/jwc

I wanted to do something like d=6+S(p)*(1+b%2), but I couldn’t figure out how to make it fit.
u/pavel

arc?
u/jwc

Hah, of course! I was originally planning on trying an effect that squeezed one axis differently than the other and gave up on that, but didn’t think to replace ellipse with something else afterward. arc makes it perfectly fit in 140 with the above revision to d. Thanks :)
u/andrea270872

Nice. I get a vibe like "beam me up!" :)
u/jwc

This looks a lot better, but probably not different enough to be worthy of a remix :)with(x)for(c.width|=b=190;p=t+b/.6,r=64-64*S(p),b--;fill(arc(960-180*(1+b%2*2)*C(p),6*b,6+2*S(p)*(1+b%2),0,7)))beginPath(fillStyle=R(r,r,r))

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.
