The Last Gun 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 open-source electronics using an Arduino microprocessor and a Raspberry Pi board.
The installation graphically charts and then musically depicts the rise & fall of annual arms exports. The flute’s aural response is based upon a value judgment. It is programmed to play a somber melody for every rise in arms exports and an upbeat tune for every year the arms exports drop.
