‘Delay’ (the official name of the piece that used XBee radios, Arduino, and some motor controllers) made its debut in Trondheim, Sweden; Clipboard Engineering was responsible for a large part of the controls (and corresponding documentation, of course). See here for the details.
Mary Sherman does amazingly rich kinetic and audio art. Clipboard’s first consult with her was on “Eri After Dark“. It is a beautiful and simple piece.
