Tafiti - a cool new way to search

If you have not seen it, check out Tafiti.  Tafiti is a swahili word, meaning "Do Research".  If you are tired of doing searches where all the results come back in a spreadsheet, then Tafiti is your solution.  It will allow you to graphically view all of your search results, save some of your favorites and even see a "Tree View" of search results.  I am including a nice instructional video for you.

 Did I mention that it uses Silverlight?
