Even the smallest sound can change the nature of a space. Listen and look at how an object changes when it is surrounded by or embedded with an unfamiliar sound.
I was able to play with sound within the Open Space project at Oriel Davies when a drawing room was created in the gallery. I planted small vibrating pellets and music boxes around the room. Sometimes I let just the smallest sound vibrate in a corner, other times I looped and layered the sounds to fill the space with a cacophony of the unknown. The room was transformed into something new and strange.
