Speed tests on my laptop:
IE 7.0.5730.13 10.1 seconds
Firefox 18.104.22.168 9.9 seconds
Safari (win32) 3.1.1 5.9 seconds
Opera 9.60 3.6 seconds
Firefox 3.1b2pre (no JIT) 2.8 seconds
Safari (win32) 2008-10-15 1.0 seconds
Google Chrome 0.2.149.30 0.8 seconds
Firefox 3.1b2pre (JIT) anywhere between 0.6-35.0 seconds
still a bit broken, but it looks like it might become a Chrome
killer sometime soon.
The code is messy, but do whatever you want with it.
If it breaks your browser, don't blame me.
Go here for something a little nicer looking,
or here if your browser's fast enough to try animation.
