Mooter: A New Clustering Search Engine:

A new search engine from Australia, Mooter Search is available in beta, although the site has gone done a few times recently. Mooter divides results into clusters with a diagram. Clicking the "Moot Quicker!" button gives the clusters on the left and search results on the right. The underlying database is not clearly identified but according to Pandia uses a combination of meta search and some of their own crawling.
