This shot of Richard Meiers MACBA in Barcelona seems to be quite random and abstract but it is created from a very rational floor plan.
"The Barcelona Museum of Contemporary Art (Museu d'Art Contemporani de Barcelona, or MACBA) is situated in the Plaça dels Àngels, in El Raval, Ciutat Vella, Barcelona, Spain.
It was designed by Richard Meier & Partners (1987-1995). The building’s architectural style has strong references to Modernism. This large (120 by 35 meters) white building has much of its southern elevation glazed, providing the visitor with views across the plaza, and allowing natural light into the interior. It includes a La Central library, specialized in art books and publications." Source : Wikipedia
