Some decades ago a German sculptor created a rather big metal sculpture which he called „Kunstwegwerfmaschine“ („machine to throw away art“). It had been exhibited in an upper level staircase of a museum in Kassel. Some days later another German sculptor went into the museum and together with his assistant they threw the „Kunstwegwerfmaschine“ down the staircases.
I still can hear the composition of this action. Can you?
