Sometime back, Sudar told about Google experimenting its UI designs. I think it's my turn today, as I had this new UI during the display of search results. I grabbed a screen shot and about an hour later, the redesign vanished. I had read at lots of sites that Google's simplistic design of the Google homepage wasn't enough to showcase their products, the result being not all their products are as popular as the search engine.
Here is the screen shot of the new layout. Look at the menu on the left. There is no menu above the search text box, which usually consists of web, images etc.
