Graphic design and advocacy and social marketing: Jay Shells
Jay Shells (Jason Shelowitz) has done some (re)design work for the Occupy Wall Street movement and has some guerrilla social marketing street signs in NYC under the sponsorship of the "Metropolitan Etiquette Authority." (Images from the Jay Shells website.)

A few years ago I saw a presentation at the National Main Street Conference which was electrifying in terms of content.
I thought that was quite interesting. It got me thinking more about the design method as a way to (re)organize approaches to planning, and is now an element of what I call action planning. See "Social Marketing the Arlington (and Tower Hamlets and Baltimore) Way."
