Moving and recombining N°2

“Moving and recombining N.2” is made of a number of interactive devices I designed.

The peculiar elements of each device are a digital recorder and a photoelectric cell which triggers the operation. The recorder can capture an audio sequence of about 30 seconds which is executed when the photocell is sufficiently lighted up and endures, repeating itself, until the amount of light is sufficient for the photocell.

A device looks like a small box (cm 7x6x10) with a loudspeaker. Usually the devices are not presented separately but in a group of at least 18 and each of them can utter a different sound sequence. The audio sequence present in the recorder can be changed an unlimited number of times so that the public could listen to different sound quality each time the system is installed. Each sound sequence has a different duration and a slight different pitch. In this way you can hear the sound that moves on the surface on which the sound boxes are placed, varying slightly its pitch.
A sound system like this one, with its numerous points of sound emissions and its potential interactivity, can be considered as a particular musical instrument that anyone is able to play.
