Is it visual art, audio art, a sculpture, a product, a machine? Byoungho Kim’s works could be described as all of these. They are visually stunning, make sounds, have a sculptural quality and they are manufactured just like any other highly-engineered industrial products. Born in Seoul, Korea, in 1974 Kim has explored the edges of art and product, sounds and visuals throughout his career. As his sound sculptures have no “practical use,” they are defined as art but their intrigue lies in the technology behind them. The two lighting fixture-like pieces we are featuring are made of aluminum and they use both piezo and arduino technology. A piezo is an electronic device that be used to both play and detect tones. arduino is a popular open-source single-board microcontroller. None of this means much to most of us, but the result — sounds being emitted and changed by the sculptures — is fascinating.
