Works for me with Firefox 1.5.0.9 but not IE 7. IE simply won't allow that javascript to be pasted into the URL box.
Edit: Correction. I tried it again in IE and it worked. Don't know why it did not work the first time; when I tried that, I had that javascript running in Firefox. I believe my computer has a dislike for running that javascript simultaneously in the two browsers. It will do it, but the motion slows down a little in IE, becomes a little jerky.
