    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.

Moving #illusion

u/pavel

Discovered this randomly when golfing the original. Not sure why it happens.
u/danny@hille.dk

cool effect: the "feature" is caused by not truncating k=--i/120 -> k=--i/120|0 disables this feature :-)
u/KilledByAPixel

👍
u/danny@hille.dk

better solution: for(i=c.width|=p=g=>(g(0)?k&3:~~k/4)*200+150*g((k&1||-1)*(i%120*41/13+5*t));k=--i/120;)x.fillRect(560+p(S),240+p(C),9,9)
