Bouchons dégradés

This is an art installation by Gilles Cenazandotti (2010) at the Pavillon de l'eau, a museum across the street from our apartment. We've been saying for ages that we'd go over and see it before the current exhibit closes at the end of the month. My aunt went yesterday and loved it so Th and I headed over today. They had all sorts of water-related art and examples of the latest water conservation technology.
