Standing at 1,729 feet tall, including its antennae, the Willis Tower (formerly known as the Sears Tower) is now the tallest building in the western hemisphere. It is not only its sheer height that amazes us, but also its glimmering glass. The style of the building is described as a combination of the art forms cubism and futurism. Cubism uses square shapes to create a picture, while futurism combines straight lines with large reflective surfaces, such as mirrors and windows.
