<canvas id=“q“></canvas>

<script type=“text/javascript“ >

var s = window.screen;

var width = q.width = s.width;

var height = q.height = s.height;

var letters = Array(256).join(1).split(‘‘);

var draw = function () {

q.getContext(‘2d‘).fillStyle=‘rgba(0,0,0,.05)‘;

q.getContext(‘2d‘).fillRect(0,0,width,height);

q.getContext(‘2d‘).fillStyle=‘#0F0‘;

letters.map(function(y_pos, index){

text = String.fromCharCode(3e4+Math.random()*33);

x_pos = index * 10;

q.getContext(‘2d‘).fillText(text, x_pos, y_pos);

letters = (y_pos > 750 + Math.random() * 1e4) ? 0 : y_pos + 10;

});

};

setInterval(draw, 33);

</script>
