The Bride Stripped Bare by Her Bachelors, Even

I'm obsessed by this piece. Actually, the piece itself I find dull, but the thought behind it, the notes, the green book -- that stuff fascinates me. And it seems I am not alone. There is something about this unfinished work rationalised by bizarre explanations that seems to make trainspotters out of all sorts...

• nice brief explanation at Tate
• an animation of the "intended" work and here and more duchamp multimedia here and even more
• THE BRIDE STRIPPED BARE BY HER BACHELORS, AS A MODEL TRAIN, EVEN
• Duchamp quotes on the bride stripped bare
