Boccioni's Development of a Bottle in Space... technically the Italian Futurists were, well, Futurists. But their stuff reeked of cubism. Just another way to skin the cat? Love it, in any case. Cubism seems to be a catch-all phrase, anyway, because I find some of it hateful and some of it astonishing, which in my self-centered world means there are too many things included under that umbrella.

By the way, the Museum für Angewandte Kunst (applied art) in Vienna has hordes of objects very like these Czech Kubismus things. In fact, I'd be a little surprised if they weren't the same guys, or at least well acquainted.
