Ungava extends tag clouds to make them a useful tool for search refinement. That is, to use a tag cloud to refine an existing query by adding new elements to the query through interactions with the cloud. As this results in a kind of drill-down search behaviour, these new clouds have been named drill clouds.

Lorcan Dempsey mentions Drill Clouds in his discussion of some interesting work being done at CISTI. They are Tag Clouds 2.0, ones that enhance the searching and presentation of results. Might be something worth considering.
