There are so many amazing social projects and movements going on these days - - guerrilla gardening, urban farming, etc...
Recently I had a conversation with a fella attempting an experimental writing project in which he left a number of journals around his city with a request that finders write a page in the journal continuing the story, leave the journal somewhere other than where they found it, and send a little line to a site he created to track the movement of the journal. So. Cool.
It sort of reminded me of Kacie Kinzer's "
tweenbots" experiment in Central Park.
