Perpetuum Mobile is a composition for a twelve-channel sound installation. Twelve loudspeakers stand in a circle. Every second a note moves from one speaker to the next, clockwise.
The center elements of the work are a red glass crystal and a flexible Fresnel lens. The project includes many reworked electronic devices – a CD-ROM, an old scanner, reused electric motors. Multiple moving elements provide a wide variability for rather primitive optical elements.
Driver is an mechanism consisting of a system of two sound circuits and auxiliary mechanical and electronic elements. The first sound circuit is a speaker emitting sound with a square wave shape. Copper balls are dispensed and fall on the membrane of this speaker one at a time or several at a time.
The adjective “fidgety” describes a nervous and jumpy feeling. Normally people see this as a bad feeling. However, the artist treats it as a musical idea.
