Tafiti Search Visualization is a Website which brings a new user experience to researching (searching and storing results). It was originally created by Microsoft to demonstrate Silverlight and the Windows Live Search APIs. Now Tafiti has been released as a Windows Live Platform Quick Application on CodePlex under a MS-PL license (free for use).
Tafiti, which means "do research" in Swahili, is an experimental search front-end from Microsoft, designed to help people use the Web for research projects that span multiple search queries and sessions by helping visualize, store, and share research results. Tafiti uses both Microsoft Silverlight and Live Search to explore the intersection of richer experiences on the Web and the increasing specialization of search.
The technologies used are Silverlight, ASP.NET Ajax, Windows Live ID and the Live Search API.
