The basic idea of this "essay" is the famous painting "Nude Descending a Staircase, No. 2 (French: Nu descendant un escalier n° 2) from Marcel Duchamp, probably the most important artist fo the 20th century.
The original picture is melting the begining of motion picture, photograhpy and painting. I add on the music of the great Yma Sumac. The scene is the big staircase of the Guggenheim in Bilbao.
