“A user can peer back in time through Zoetrope in several ways. Simply pulling a scrollbar at the bottom of the browser winds a Web page back to show what it looked like hours, days, or months ago. Or, if the user is interested in one specific piece of information, like the price of a certain product, he or she can draw a “lens” over that area of the page to see how it changes. An experienced user can perform even more-advanced analysis. For example, configured correctly, Zoetrope will recognize a price as it goes up or down and will show the results as a graph. It’s also possible to draw lenses on different websites and sync them in order to carry out a historical comparison.”
