Hmm, Letty, not sure. If the guy was actually playing his arm, that would be geeky, but not technichally 'air', and part of the geekiness of this thread is being geeky about proper 'air' terminology. Ergo the magazine....also actual playing.
Air triangle? Nah that would be cute. Air recorder. Yeah. That would be "geeky".
Anyone up for some air koto?
