Hasan Jamil has released PhyQL, a visual system for querying phylogenetic information. To quote from the web site: There is also a YouTube screencast: I haven't had a chance to play with it yet. PhyQL was originally described by Jamil et al. "Querying phylogenies visually", BIBE 2001 (doi:10.1109/BIBE.2001.974405).
