The pavilion in silver resembles a huge metal bowl along the Huangpu River in the Puxi section of the Expo site. Its external spiral design conveys a sense of modernity. The metallic design as well as the smooth and fluid lines of the pavilion's exterior is evocative of an automobile body. The pavilion exterior is cloaked in 4,000 recycled aluminum panels of slightly different sizes, tilt angles and surface cambers to give its outer shell a smooth and seamless appearance.
