When the World's Fair, the World Cup or the Olympics come to town, neighborhoods are cleaned up and ostentatious architecture rises up as the world's eyes fall on the chosen city.
Photographers Gary Hustwit and Jon Pack have just launched their new project, a photographic examination of what the Olympics leave behind when they leave a city.
Just hours after launching the project on Kickstarter, the photogs have already raised $3,000 for what looks like an awesome book.
Last year, Hustwit, who was doing crowdfunding before it was cool for his films "Helvetica" and "Objectified" launched his first Kickstarter campaign for his film "Urbanized," about urban design. The campaign ended up raising over $100,000.
Watch the pair's Kickstarter video below, where they show off some of the work they've shot and talk about the project:
