10 x 10 is an interactive photo capture of what's going on in the world, every hour. From the site:

"Every hour, 10x10 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, 10x10 leaves a trail of these hourly statements which, stitched together side by side, form a continuous patchwork tapestry of human life."

It's gorgeous, moving, sometimes disturbing, always thought-provoking.
