Ji Lee of Pleaseenjoy.com is running a fun and potentially illegal project: The Bubble Project. The goal is to have people download various templates he's created in the shape of cartoon talking balloons, and paste them onto street advertising and to put provocative, funny, or ironic content in them.

Lee plans to collate images that people take of these tags into a book.

His idea is that we need to take back public space from the corporations. Remember, though, that the well known graffitti artist John Tsombikos, known as "Borf," just pleaded guilty to felony destruction of property, and will be doing hundreds of hours of graffitti clean-up, even if he avoids jail.
