LC Graffiti and Street Art Project was produced by Lewis & Clark College's Watzek Library and Off-Campus and Study Abroad Program. It was an experiment to develop and employ mobile technologies for teaching and learning with the expectation that it might serve as a model for creating collaborative digital image projects with mobile devices and Flickr for non-traditional classroom settings. Students used digital cameras, smart phones and social software to document and catalog the ephemeral graffiti and street art throughout the five boroughs of New York City in the Fall of 2010.
