Semaphore Mobile recently developed a new application, All City Art, essentially a handheld mobile guide to global street art. Addictive and accessible, the application is ripe for graffiti enthusiasts and the average voyeur alike. Easily tag and upload street art spots you find and discover new ones you haven't seen yet. And, connect the dots. With splashes of urban visuals spanning the globe, the application encourages users to make connections and learn about artists via their biographies. Check out Banksy's early work in England and his transatlantic antics in New York. Or, trace Swoon's evolution on the lower east side.
The fact that my nephew first clued me into this application may account for part of its attraction----it makes art accessible and brings global voices into focus, pulling together trends, new ideas and international movements and styles.
