A participant view of feather wings as they move in concert with the the participant's breath. Inspire, and the wings swing away. Expire, and the wings return. The movement of the wings are fully linked to the participant's respiratory pattern. A tiny breath and the wings move just a bit. A deep inspire and the wings fully open. When panting, the wings flutter. Wings track respiration via changes in center of gravity of the chair. The center of gravity changes because respiration involves displacement of mass in the participant's thorax and abdomen.
