Check out 10 x 10.

From the site:

10×10™ (’ten by ten’) is an interactive exploration of the words and pictures that define the time. The result is an often moving, sometimes shocking, occasionally frivolous, but always fitting snapshot of our world. Every hour, 10×10 collects the 100 words and pictures that matter most on a global scale, and presents them as a single image, taken to encapsulate that moment in time. Over the course of days, months, and years, 10×10 leaves a trail of these hourly statements which, stitched together side by side, form a continuous patchwork tapestry of human life.

10 x 10 grabs the RSS feeds of some news sources and every hour it takes what it perceives to be the most important words, along with the images associated with those words.

It then serves up a grid of 10×10 images and words in a very nifty flash interface that is cute to explore and check out the news stories.

You can also browse through the history. It’s been around a while, but I only just found it!
