The Cloud Gate is a public sculpture and is the centerpiece of the AT & T Plaza at Millennium Park in Chicago, Illinois, United States. This work of art seems an object arrived from another planet and deposited in a mysterious way inside the park. It was inaugurated in 2006, but very soon the public made it their own and started calling it "The Bean", due to its bean or bean shape. Sculpture is today an object of contemplation and play. Its enormous glossy gently curved surface, which reflects the reality of the environment, invites to be contemplated. In addition, this huge mirror of magic curves, has the ability to make us go back to childhood, because we soon enter the game to start looking for us among their reflections. The sculpture is very popular among tourists, who take the opportunity to take photos of an object with unique reflection properties.
