Nice. Here's 126, maybe room for snowflake code with(x)for(fillRect(0,0,i=2e3,i);i--;)clearRect(50,9,!setTransform(s=2+i%7,0,0,s,i,i&&(i*i+t*s)*50%2e3-400),i&&!rotate(i+t/4))

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.
