Music Pen is an experiment from a Ball-point pen transformed into sound tool. The stake was to leave the pen its whole feature, that is the possibility of leaving a trace. However, by equipping it with connections welded in the mine, the latter behaves, once connected in an amplifier, as any jack cable. Support of a cartography and an interface, the body welcomes the image and sends back the sound simultaneously.

This project was a trigger in the conception of Jack duo, with Émilie Pouzet.
