San Francisco based artist Bernie Lubell’s wood sculptures are some of the most inspirational kinetic art pieces around. His latest, “A Little Breathing Room” (2007), connects a custom built wooden bicycle to a large wood blower that causes a latex wall to “breathe”. The air also produces a tone in a 10′ wood organ pipe. It also allows for a second person to effect the tone theough interacting with the latex sheet. Really nice example of a collaborative instrument that can double as a fitness machine.
