Marcel Duchamp

Duchamp created some art work that was playfull when first built but if you were to go and do what was 1st intended with it you would be fround apon.

This image shows Duchamp's 16 miles of string. It was in a gallery in New York at White Reid mansion in 1942.  (it was the frustration, not the elimination of sight that Duchamp desired)

This image shows one of Duchamp's exhibitions where he decided to hang 1,200 sacks full of coal from the ceiling.

This is Duchamp's Bicycle Wheel (well a remake as the original was lost). The idea behind this is that you are supposed to spin the wheel.

This was said in an interview with Duchamp in 1960 about the Bicycle Wheel;

"To set the wheel turning was very soothing, very comforting, a sort of opening of avenues on other things than material life of every day. I liked the idea of having a bicycle wheel in my studio. I enjoyed looking at it, just as I enjoyed looking at the flames dancing in a fireplace."
