The Keith Jarrett style was amazing - I really felt the analogy between playing a live instrument and changing the code in real-time, and it sounded very good.
I had visions of a large symphony hall with people dressed very sharply watching a master 'player' create and manipulate this piece in real-time... I think there may be a possibility. Interesting thought anyway.
