The Degree Confluence Project is an attempt to collect photographs and descriptions of the world at the confluence of lines of latitude and longitude. It's completely arbitrary of course, but still pretty neat.

There are quite a few people out there trying to help complete the project, hiking to remote places with GPS devices to score their photos (some making quite a celebration out of it - dig the outfits). Still, the remotest areas of the world remain unphotographed.

Someone's put together a mosaic of the points so far collected: [click here] Quite cool.
