  • pavel: This does look great :), not sure what else to add with the spare chars
  • qm3ster: Nice! I limited it to 100 particles, each gets 20 movements per frame now:
  • qm3ster: for(r=Math.random,w=i=2e3;i--;x.fillRect(p[0]+=2-4*r(),p[1]+=2-4*r(),2,2))p=u[z=i%100]=u[z]||[a=w*r(),b=w*r(),R(0,a/8,b/4)],x.fillStyle=p[2]
