Have you noticed the difference in Google Newer Look. Beside changes on the image logo and layout, one thing I spotted is the Wonder Wheel search. It look and feel innovative. To trigger the Wonder wheel, look on at the left panel and click on Wonder wheel. From there onwards, let the wheel drive your searches.
When you are doing a keyword search, instead of a branched out search (something like Windows Explorer), Wonder Wheel offer a wheeled perspective and lead you to another clusters of suggested keywords, all represent in wheel spokes. It look better and friendly to the eyes.I won't be surprised if this Wonder wheel is copied and used in future Windows desktop.
