Kontrol is an experimental music toy by Johan Halin, a minimal techno composition where you control both the visuals and musical structure. The application was developed by Ab Parasol Oy. To make things happen, slowly push the blue buttons.
I always thought of AppStore as a great platform to publish music. This is a great example of how music on a digital device should sound/play. See also Re<ords.
