<h1>Windows Longhorn Glass Look</h1>
<p>This page uses no images, except the background image. Everything is done with
HTML, CSS, a bit of JavaScript and a lot of Internet Explorer filters.</p>
<p>Yes, it's slow, but it's pretty isn't it?</p>
<p>Looks horrible in any browser but Internet Explorer.</p>
