This building by Jean Nouvel is in Barcelona, Spain and as you can see, at night it is beautiful.  The lights that illuminate the building provides cool scenery for the city and in quite a cool shape. The building has a profile similar to that of a bullet from a gun. The reason I like this building so much is because it is a corporate building! Most cool looking buildings are museums but it is not often that a company whose focus is typically making money to have an art piece for a corporate headquarters.
