Do you know a good storytelling-project?

I need your good, clever and creative minds: In relation to my master thesis I’m working with storytelling in urban planning.
> As a start storytelling is understood in its broad sense: the use of film, pictures, happenings, words, interventions etc.
> It has to be a project where the storytelling helped people change behaviour or think differently about a place, people or phenomenon.
> The project should be used as part of a bigger process or/and as a result of a process.
