Every single sound made from this kinetic installation serves as proof of existence of some unknown space as well as a reminder of the irregularities inherent to the conditions of human existence. I want to emphasize that any experiences of deja-vu one may have, which seems to involve a certain level of repetition, familiarity and regularity, is in fact influenced by many independent random factors. This piece of sound installation tries to fundamentally reconstruct our external world which is based exclusively on sounds and independent from any temporal or spatial context in order to convey a sense of uncertainty which is itself a consequence of irregularity. （Kuo I-chen）
