Vicious Circular Breathing is a hermetically-sealed apparatus that invites the public to breathe the air that was previously breathed by participants before them. Commissioned by Borusan Contemporary in Istanbul, the installation consists of a glass room with double sliding doors, two emergency exits, carbon dioxide and oxygen sensors, a set of motorized bellows, an electromagnetic valve system, and 61 brown paper bags hanging from respiration tubes. In the piece, visitors� breath is kept circulating and made tangible by automatically inflating and deflating the brown paper bags around 10,000 times a day, the normal respiratory frequency for an adult at rest. There are 61 bags because that constitutes 5 octaves which is a typical range of musical organs which inspire the design. The piece includes warnings for asphyxiation, contagion and panic, and produces a faint mechanical sound, a quiet whir from the air flow and a louder crackle from the crumpling bags. To participate, an audience member presses a button on the outside of the glass prism. They can then enter a vestibule and wait for it to be decompressed. Once they enter the main chamber, they sit down and breathe the recycled air.
