A Diebold Opteva 562 cash dispenser has been set into the centre of a pipe organ for an art exhibit titled “Algorithm” at the U.S. Pavilion for the 54th International Art Exhibition.

Each financial transaction that visitors conduct generates a unique musical score that produces randomized notes and chords at varying degrees of volume by driving pressurized air through pipes selected via the ATM keyboard.

I bet the notes are not truly random.

And the second thing that comes to mind are the televangelist priests begging for money and keeping two sets of accounting books. Not sure if that was the idea.
