Because I'm a fan of the new Google UI seen in Gmail, Docs, Calendar, etc, I decided to reproduce the look of these new UI elements for my own personal use.
This is being tested in the latest versions of Chrome and Firefox only. I have no immediate plans to test this in IE.

The foundation of the CSS was borrowed heavily from the css3-github-buttons project. And of course, Google.
