Pivot - An experiment from Microsoft Live Labs

Pivot is a way to interact with massive amounts of data, available at this link. It requires Silverlight.
Pivot makes it easier to interact with massive amounts of data in ways that are powerful, informative, and fun. We tried to step back and design an interaction model that accommodates the complexity and scale of information rather than the traditional structure of the Web.
When we use the Web today we treat the most fundamental scenarios as separate activities. Search takes us from many things to one, browsing moves us from one thing to another, and recommendations expose affinities that enable us to explore related topics. Can we do better by combining these scenarios into a more unified experience?
At the heart of Pivot are "Collections." They combine large groups of similar items on the Internet, so we can begin viewing the relationships between individual pieces of information in a new way. By visualizing hidden patterns, Pivot enables users to discover new insights while interacting with thousands of things at once.
