prinpl / barrel organ player

Prinpl is a music player with the principle of the barrel organ. Through the generalization of 3D printing it could be possible to reproduce the playing of big and complex barrel organs. Instead of direct playing the user can print his favorite song in the shape of a CD with dots. He can collect it like the LP in the old days and watch prinpl play it. The old records could be reproduced through new technology. Prinpl can also distinguish a normal CD and the prinpl dot-CD and play both.
