100 windows.

10x10 is... well, here's how its creator describes it:

Every hour, 10x10 scans the RSS feeds of several leading international news sources, and performs an elaborate process of weighted linguistic analysis on the text contained in their top news stories. After this process, conclusions are automatically drawn about the hour's most important words. The top 100 words are chosen, along with 100 corresponding images, culled from the source news stories. At the end of each day, month, and year, 10x10 looks back through its archives to conclude the top 100 words for the given time period. In this way, a constantly evolving record of our world is formed, based on prominent world events, without any human input.

Totally disingenuous of course, but a cute idea. By parsing Reuters World News, BBC World Edition and the New York Times International News, it does manage to collate some interesting leads and the interface is shiny, but the project remains thin and unsatisfying. As a taste of the future, it's appealing; as a viable news sorter, it's definitely limited.
