The New York Times published photos of Jean Nouvel's design for the National Museum of Qatar. Nicolai Ouroussoff writes about it here. Photos from the article.
It's design is based on a "desert rose." That's a crystal foration that occurs during the evaporation of salty bodies of water in arid, sandy conditions. They are classified chemically as gypsum. (For sculptors, plaster is a kind of gypsum.)
Beautiful inspiration from the natural world to create the man made world.
