This can be rendered directly into Chrome by:

    data:text/html, <canvas id=q style=margin:-10><script>for(q.width=q.height=b=3000,m=Math.random,p=[],i=0;i<256;p[i++]=1);setInterval('9Style="rgba(0,0,0,.05)"9Rect(0,0,b,b)9Style="#0F0";p.map(function(v,i){9Text(String.fromCharCode(3e4+m()*33),i*10,v);p[i]=v>758+m()*1e4?0:v+10})'.split(9).join(';q.getContext("2d").fill'),33)</script>
