I did this short code in order to generate some sculptural shapes:
http://www.openprocessing.org/visuals/?visualID=37690The purpose was to generate nice prints (via sunflow)... I´ve to say code there is really rough, there are better methods if you want to get music data into the skecth... just search in openprocessing and you will find a lot of stuff regarding this topic...
You can check also these ones, but they are part of an unfinished project, and I have to improve/rethink the output slightly:
