A while back, I reviewed several desktop content search engines, as faculty on campus had desired something better to search all the research they had collected on their PC's. We recommended X1 for most users, and ISYS for advanced users. Since then, google of course released google desktop search as well.
One of the things that a faculty member suggested at the time of our investigation was perhaps a better way to search the internet from their desktops as well. So I included Grokker, which was sort of a new face on search. A fancy way to view results by visual categories. Categories are built in, or you can define your own. The only bummer was the technology was limited to Windows.
Now they have released a web based grokker which appears to be a Java applet with most of the same functionality as the desktop version (except of course indexing your desktop content). It uses the Yahoo! search engine.
Anyway if your looking for an interesting way to view search results, check it out.
