Google unifying their product UI's

A few months back, google changed the login UI for their products. Recently they started pushing the new - look and feel inside their products (docs, calendar, blogger) and still a lot more to come. The new UI is based on HTML5, it has a nice, clean look and navigation.

If you want to enable the new look, click "Try the new look" option on the top right corner and "Switch back to old interface" to change back.
