You could also adapt
www.polyarc.us/radar
to do it.
It uses transparent GIFs but it could use transparent PNGs with the
following simple change:
if (window.XMLHttpRequest)
{
e.src="whatever";
}
else // IE6
{
e.style.filter="progid:DXImageTransform.Microsoft.AlphaImageLoader
(src='whatever',sizingMethod='scale')";
}
