“Faire la peau is a suspended score for bodhràn. The bodhràn is an irish instrument. This drum allow a huge and subtle sound variation.” More on this here (in french) : http://www.elcordonnier.lautremusique.net/3.html

I turned the drum into a sensitive display. Man can move the score projected on the drum with his fist and play sound with his fingers. The device is based on video tracking, like most of wide DIY touchscreen.
