The site is called 10x10 and offers an hour by hour "postcard" (updated hourly) based on the 100 most "important" words culled from three RSS news feeds.
The feeds come from:
+ Reuters World News
+ BBC World Edition
+ New York Times International News
Here's how Harris describes 10x10, "Each hour is presented as a picture postcard window, composed of 100 different frames, each of which holds the image of a single moment in time. Clicking on a single frame allows us to peer a bit deeper into the story that lies behind the image. In this way, we can dart in and out of the news, understanding both the individual stories and the ways in which they relate to each other."
10x10's word lists and postcards are built without any human intervention.
Links to archived hourly snapshots and word lists are available (look for the links directly below each snapshot).
