Data and Design Collide in Foursquare Check-In Maps

Data and design collide with these Etch Maps from Jeremy Weikel and Michael Yap. Each map is a customizable visualization of your personal Foursquare check-ins and serves as "your unique story of exploring your favorite cities." The maps are currently available for Manhattan, San Francisco and Portland. I can't help but think what a great souvenir one of these would make for a trip to one of these cities.
