Google's new layout?

While I was searching thru the web with google, all of the sudden I noticed that the layout of search results from google seems to be somewhat different! Google is known to run tests on unsuspected people. When I first saw this layout, it was quite useful. It almost had similar feel as the google desktop application.

Also, it seems like I wasn't the only one who saw the new layout. Check out the story on techcrunch.
