Buried in yesterday's Slashback on Slashdot was a link to an incredibly cool project. But I usually skip Slashbacks, so I didn't notice it.
Luckily, when I got in this morning, The Degree Confluence Project was on my officemate's screen. This project seeks photographs from every integer latitude/longitude intersection on the planet. They have all but a few in the United States, Europe is pretty well covered, and they have other interesting spots including 0°, 0°. Amazing.
