This is one of the most creative uses for an iphone I’ve seen so far.   RjDj is an iphone/ipod app that uses your motion and the sound occurring naturally around you to make music. The application takes samples through the built-in microphone and uses input from the accelerometer and produces songs.

This is remarkable because it’s not just a new way of making music – it’s a whole new music GENRE – "reactive" music. This reactive music even uses a different form of arranging called "scenes" which have no definite beginning nor end. The music is a product of the environment and even the listener themselves.

People who have tried this new app describe it as very addictive and almost like being on some sort of digital drug . It also can cause "mind twisting hearing sensations which affect the listeners sensory perception."

This opens up all sorts of possibilities… I’m excited to see what else comes from this. More info here .
