CSS3 Navigation Menu

I was a little bored so I figured I'd give turning this into CSS/HTML a shot! You can see the result here.

The HTML for it is real simple; it's just an unordered list, and the CSS adapts to any size list. You can play around with it here.

Of course this is WebKit only, and I only tested in Safari 5.1. Also, I couldn't figure out the font so I just used Helvetica.
