With thanks to Michael-in-Paris we just discovered the Pommery Champagne house in Reims, France (photo via Wikipedia): When there, be sure to get a tour of the cellar. That's where you'll discover their contemporary art collection, which features an installation work composed of a pair of Les Pauls, Big Muffs, Marshalls, and a lot of birds.

The gear is left plugged in, and the birds actually "play" the guitars when they land on the strings. Michael wasn't too keen about the bird guano on the instruments, but c'est l'art:
