NO AD is an app for smartphones and tablets that enables users to project artworks over the advertisements and transform the New York subway into a personal exhibition space. For the project the makers have worked with over 50 artists, including some big names from the street art and graffiti scene. This makes the project even more interesting. It generates a way to explore truly great works of digital art, varying from digitized paintings and collages to photography and fine art. Among the works are also some short movies and digital remakes of graffiti artworks from the past, such as Haring’s Subway Drawings.
