  • heheh: I was playing with the Array Initialization Array(10).fill().map((o,i)=>i) shaved off 2 bytes... but then (after mentally padding my own shoulders) [0,1,2,3,4,5,6,7,8,9] 🤦‍♂️
  • u/danny@hille.dk
    c.width=99,x.fillText(a=t%4<2?Array(10).fill().map($=>Math.random()*9|0).join(''):a,22,35)
  • u/danny@hille.dk
    81 bytes but with commas: c.width=99,x.fillText(a=t%4<2?Array(10).fill().map($=>Math.random()*9|0):a,10,35)
  • u/Xen
    77: x.fillText(a=t%4<2?Array(c.width=99).fill().map($=>Math.random()*9|0):a,9,35)
  • u/danny@hille.dk

  • C64 style copperbars/rasterbars
  • u/Xen
    love it
  • u/danny@hille.dk
    much better version:for(w=c.width=200,x.fillRect(0,0,w,w),q=5;q--;)for(i=9;i--;)x.fillStyle=hsl(${q*50},70%,${99-Math.abs((i-4)*20)}%,x.fillRect(0,9+S(C(t/9)+S(t*2-q))*9+i,w,1);x.fillText('C64',94,18)

    if you want 'correct' scroll direction: w=c.width=400,x.fillRect(0,0,w,w),x.fillStyle=R(0,w) for(Y=32;Y--;)for(X=44;X--;)x.fillText(String.fromCharCode(0x30a2+(t*X+Y)%90),X*9,280-Y*9)
