Animina is an interactive soundwalk of Philadelphias Race Street Pier created by The Mural and the Mint. Go to Race and Second Streets, launch the app, put on your headphones, put your phone away and start walking east toward the pier and back again. Each part of the journey has its own disctinctive audio experience. You must be in the appropriate place to experience this app. Continued use of GPS running in the background can dramatically decrease battery life.
