+			<p>Lucy model from <a href="http://graphics.stanford.edu/data/3Dscanrep/">Stanford 3d scanning repository</a> 
+			(decimated with <a href="http://meshlab.sourceforge.net/">Meshlab</a>).
+			<p>Please be patient while the mesh is loading. It may take a while, it's 4.5MB file.
+			<p>Using a modified version of <a href="http://github.com/alteredq/three.js">Three.js</a> by mrdoob.
+			<br/>
+			<p>Best viewed in Chrome 8/9 or Firefox 4 using WebGL renderer.
+			<p>Canvas renderer is very slow for this demo and only diffuse material works there.
