Grokker - A New Way to Look at Search. Very nice visual search engine that requires Java. You can try the online demo version, download and try or buy it. This search tool has some interesting features, like Delete links you don't need, add ones you discover on your own, create new categories, rearrange results, customized filters, preview balloons, explore any subject far beyond the obvious and opically organized categories and subcategories with simple zoom-in/zoom-out navigation. And do I have to say that I love the design and colours? (via 8 Ways to Sunday)
