The Google Wonder Wheel is an expansion to the Google search that I heard of recently that allows searches to have a different user interface that automatically suggests multiple related searches and displays them in a kind of chart form. You really have to try it out to understand. All you have to do is run a Google search. Then, on the page that gives the search results, under the search bar, choose “Show Options”. In the options, select “Wonder Wheel”, and presto, you have the Google Wonder Wheel at your command. The results of each search are displayed to the right of the wheel.

You can see it in action here with a search of the people at the U.P. Web Maestro.

You can also use the same feature with Google Image Swirl. Check it out here.
