Tag Galaxy provides a very visual tag-based search tool for Flickr – check it out. IMO Google really needs to start working (they probably already are) on more visual search tools like this for the Web. Browsing search results like this provides a better, or at least more interesting, user experience. If Google is working on this kind of thing – they should start releasing some of the work as Google Labs projects. DIGG also sports cool visual search tools. WARNING: Tag Galaxy was built by Germans so watch out for David Hasselhoff avatars.
