    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

    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

    drop in a t*=3; to hurry it up. change "with(g." to "with(c, " while remixing. change c back to g before posting.

  • safer for editing #webgl
  • u/IV
    manga's original is grand, this is safer than my previous attempt in terms of editing and not getting errors which cause a reload :)
  • u/IV
    the prblem with this is that youd have to clear both contexts which costs more bytes

  • testing remix of d/1948
  • u/IV
    correction: remix of d/19498. The problem with this is in replacing the canvas. Any attempt at a remix will fail to get the context. But it is shortest :D
  • u/nikoloffgeorgi
    u/IV that's really cool. i wonder if anything beyond animating the color uniformly can be done within 140 chars
  • u/IV
    nothing you cant do better with the canvas. try this: with(c.getContext('webgl'))(enable(0x0C11),scissor(i,i,i,i),clearColor(C(t),S(t),t,1),clear(16384))
  • u/IV
    what we need is a glitter, with a quad shader set up and then we can play with 140 chars of a fragment main
  • u/IV
    u/nikoloffgeorgi game-on! i did this: d/19541
