The Boing Boing blog made me aware of this excellent site - Making sense of Marcel Duchamp.
It's a guided tour of Duchamp's work. The elegant design is an immediate recommendation. But what I particularly like is the commentary - particularly, pointing out Duchamp's sense of comedy, and the way he subverts artistic forms.
'The Bride Stripped Bare by her Bachelors, Even' is deconstructed, and made to operate as a sort of perpetual motion machine through the use of cartoons that interpret Duchamp's original designs (not all of his ideas made it through to the final work).
And there's a timeline which makes it easy to see where Duchamp's works fit in the overall progression of his art.
The technology is a perfect fit with the content. You can't say that about many websites. And I really do feel, having spent half an hour with the site, that I understand a lot more about Duchamp - an artist I previously knew only for the famous (or rather notorious) urinal. I like him a lot more, too.
