F.A.C.E.S is conceptual street art project which have never been realized. It was a big black cube (5 m) with moving faces. Each face is like a board of pins that can be pull and push each individually. We build a 1.2m prototype and show it in Chalon dans la Rue in 2009.
I was in charge of the sound design. I used 4 small cheap mid-range loudspeakers behind each face, one horn tweeter at each corner on the top and a big subwoofer inside. A Max/MSP patch drives both the PA and the motors.
