If you have not yet checked out 3191 (it tops the list to the left there), I heartily encourage you to do so. 3191 is a "visual blog" -- no text, just daily photographs taken by two friends each morning, 3191 miles apart. They do not coordinate the photos in any way, they each simply photograph their morning and post. Yet the photos are invariably and amazingly complementary to each other, and they're always serene and simply beautiful. It's like a little visual breath, each day.
