Independent developers Scott Snibbe and Lukas Girling announce the release of a new app for iPhone and iPad that turns music into a form of interactive game. The app, playfully called OscilloScoop, presents a trio of brightly colored stacked spinning crowns. Touching a crown trims or builds up its edge, like a spinning disk of clay. To a trained musician, OscilloScoop can be broken down into understandable musical elements. The top ring controls the melody, or choice of notes.
