Chifte Kavali (Double Barrel Flute) is a mechano-robotic flute built out of a disabled shotgun and salvaged industrial components. The gun barrels have been transformed into a double-flute, which is played by compressed air. The mechanics are programmed and controlled through the use of open-source electronics using an Arduino microprocessor.
The installation graphically charts and then musically depicts the rise & fall of annual U.S. arms exports. The flute’s aural response is based upon a value judgment. It is programmed to play The Band Played Waltzing Mathilda for every rise in arms exports and Beethoven's Ode to Joy for every year the arms exports drop.
