Clusty,™ is a new internet search engine from Vivisimo. It provides a new method of presenting results. Using the Vivisimo Clustering Engine,™ it automatically clusters results into categories that are intelligently selected from the words and phrases contained in the search results themselves. These categories strive for human-level accuracy and offer hierarchical drill-down capability in a familiar and intuitive folders-style interface. There are no more long, mind-numbing lists to scroll through. It's worth a try...give it a go.
