Zlote Tarasy or Golden Terraces, an iconic, undulating, glass-roofed building in Warsaw, Poland, is seen in 2006. The building is an example of 'blobitecture,' a term first used to deride the style but that has since stuck. Due to its complex, organic shapes and unique engineering challenges, blob-architecture structures require the aid of computers to design. Jerde Partnership/PRNewsFoto/Newscom/File
The Guggenheim Museum Bilbao, a contemporary art museum in Spain, was designed by architect Frank Gehry. The rolling, metal curves of the building are designed to catch reflected light, and were designed with the aid of computer simulations. The building has been called a spectacular example of deconstructivist architecture, but Gehry denies association with that particular movement. Miguel Raurich/Newscom/File
