I converted my entry (http://www.dbfinteractive.com/forum/index.php?topic=6136.0) for last year's Christmas competition to WebGL, you can check it out here: link (http://goremotel.com/dasher) (or download the attachment).
It should work properly on the latest versions of Chrome, Firefox and Opera for Windows.
It's running nice and smoothly over here.
That is awesome, works well. I really need to look at that WebGL stuff when I get a chance. You should make this into a game. :)
