I am thinking that I didn't post this after the discussion.......if not I apologize- if I did, I apologize for the duplicate post!!
Duchamp's "Nude Descending a Staircase" inspired works I use together on an ART INSPIRES bulletin board.....

There are also a couple of songs "Naked Girl Falling down the Stairs" by the Cramps and instrumental on Bruce Cockburn's music album Life Short Call Now (2006).
This site has a number of homage pieces, but you need to check it first as it notes "While, given the subject matter, some nudity will be inevitable, there will be no gratuitous nudity on these pages." snap-dragon.com/duchamp
