It is hard to explain on paper, but you can see a brilliant video of the application in action.

A user can create lenses on the website, for example, focusing on the price of a DVD at Amazon, and see how the price went up and down over the coming months. More interestingly, you can link lenses together across different websites, and for example, see how the price of gas was affected by say, the aggregated google news result of 'war.'"
