a structure based on infrasound, dealing with rhythm, prime numbers and overtones.
the speakers are fed sinewaves at inaudible frequencies causing them to move. overtones within audible range, calculated from the initial frequencies, are introduced with time intervals of prime numbers, making sure the behaviour of the structure is (almost) never the same.
