We went to the Luxembourg Museum and there was a fairly arbitrary exhibit of modern art there called "From Miro to Warhol." That's a lot of ground to cover, when you think about it. And all they'd really done, it seems, is borrowed some art and picked from it a big, early name and a big, later name and themed the whole thing as a progression between the two. PR it, postcard it up for the gift shop and - voila! You, too, can be a curator.
There was a metal sculpture there by Jean Tinguely called "The Indian Chief" and every 20 minutes or so it would shake and vibrate like the dickens and scare whoever happened to be scrutinizing it at the time half to death. It made a godawful racket and anyone who hadn't experienced it yet would start like they'd just heard a stack of dishes collapse in their kitchen.
