The ever interesting Music thing points us at a brilliant project from Noah Vawter at MIT. It's called Ambient Addition. It's a walkman-like device that listens to the sound around you and turns it into music on the fly. It filters the ambient noises through a vocoder and pre-arranged chord patterns to give you harmony and takes more stacatto elements and transforms them into rhythm tracks. It's genius. You can still be of the world around you, but listening to something melodic, harmonic and rhythmic. It's best explained by his video here.
