"In April 2009, we sent a personal, handwritten letter to each of the 467 households in the small Irish village of Cushendall." Now, Michael Crowe and Lenka Clayton (previously on MeFi) intend to send a letter to everyone on the planet.

Return to sender: Artist puts Royal Mail to the test - "To put them to the test, Harriet Russell concealed the addresses of 130 letters to herself in a series of increasingly complex puzzles and ciphers. Among the disguises she employed were dot-to-dot drawings, anagrams and cartoons. The answer, it seems, was very far indeed. Amazingly, only 10 failed to complete their journey back to her." Be sure to click the "more pictures" link to the right for more samples. Via one.point.zero.

Cool collective art. This project takes blank slate real-world media (journals, t-shirts, books, etc..) and snail mails it around to participants who add to the work creating a collective piece of art. It aims to replicate what happens on-line, MeFi for example, but using real-world objects and postal mail.
