The bubble project is a pretty interesting one. People put empty bubbles on public display advertising – which encourages others to fill them out – click here for the bubble project manifesto. The filled out bubbles are then photographed and displayed on the bubble project’s web site. Next year there are also plans to have them published in a book.
I am not sure that I would call this an open dialog with the advertisers, but it does make for some interesting results.
