Promote a city guide through photos taken by tourists
Tourists usually see the city or place they visit for the first time in a totally different way compared to citizens or habitants of that city.
Along with the the idea suggested by JR's TED Prize wish, the idea is to have a series of picture taken throughout one year by each person as they travel to new places. All pictures will be gathered and assembled in a series that will be placed in airports, city hall, museums, etc.. to show the city the way visitors see it.
I think it would be a very different view
