In Sale Away, passers-by can conduct an “orchestra” of household devices via their mobile phones on a display window.
The mechanical orchestra consists of flute, organ and brass playing vacuum cleaners, rattling kitchen mixers, buzzing ventilators, radio playing toy trains, wobbling jigsaws, dancing tumble dryers, humming refrigerators and other misused household utilities.
The conductor is a big refrigerator. This fridge is also the explanatory interface. To start the orchestra and wake up the shopping windows you have to dial the number and follow the commands displayed on the window. This call opens the door of the fridge, giving free the image of its explanatory interface, the “mobile phone robot person”. The robot will explain and invite you to act. By pressing keys on the phone you can let all different instruments play along with the melody. You can set some single voices or the whole orchestra tutti.
