Lockergnome goofy faces

So I was on Chris Pirillo's site today and whipped up a goofy script. Enjoy.

<div id="divContainer"></div>
<script type="text/javascript">
var img = document.createElement('img');
var ct = 1;
var div = document.getElementById('divContainer');
setInterval("ChangePic()",100);
div.appendChild(img);

function ChangePic()
{
img.setAttribute('src', 'http://chris.pirillo.com/images/heads/large/' + ct + '.png');
ct = ct >= 28 ? 1 : ct+1;
}
</script>
