    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 think someone did a compressed one already. This one is 193B: t||(C=12,N=90,m=0);for(n=[i=N*N];i--;){u=i%N;v=~~(i/N);for(S=z=9;z--;S-=m[(~(z/3)+2+u)+(z%3-1+v)*N]|0); x.fillStyle=R(s=(n[i]=m?S-5?S==6|0:m[i]:new Date%2)*255,s,s),x.fillRect(u*C,v*C,C,C)};m=n
u/IV

I have a toroidal version of 172B (166 without the wrapping) using a shorter draw, but the compressor doesnt like it: t||(C=12,N=90,m=0);for(n=[i=N*N];i--;){u=i%N;v=-~(i/N);for(S=z=9;z--;S-=m[(~(z/3)+2+u+N)%N+(z%3-2+v+N)%N*N]); x.fillText('⬛⬜'[n[i]=m?S-5?S==6|0:m[i]:new Date%2],u*C,v*C) };m=n

Primordial soup #gameoflife (with changed rules to fit 107 bytes). Homage to John Conway (1937-2020), the creator of Game of Life and cellular automata, seed of ideas for Artificial Life, emergence, self-organization and complexity.

u/tomxor

Farewell John Conway, not his favorite discovery, none the less responsible for generations of programmers enjoyment.

Nice! beat me to it, although i'm doing something slightly different... progressing at a rate of -4 chars per day :P

This grid takes about 850 generations to stabilize between 2 states! "Theoretically, Conway's Life has the power of a universal Turing machine: anything that can be computed algorithmically can be computed within Life."
u/DaSpider

Clicking tags I realized the sheer number of cool #gameoflife dweets of times yore. 😲
u/tomxor

Yup, some of the oldest ones from 2017 are quite impressive and completely ucompressed, although that tag is a bit polluted with serpinski triangles later on.
