Created for the 1991 Mayfest, Native American artist Robert Haozous created a great sculpture named “Artificial Cloud.” The sculpture is 72.5 feet tall, the work was created on the premise that more people would look at a naturally rusting steel cloud than at the real thing. The Tulsa Convention and Visitors Bureau website describes it as "a silent commentary on man’s love of technology and the destructiveness that can come from that infatuation. The surface of the sculpture has been allowed to rust, to show the effect of time and the atmosphere." Haozous' concerns about the state of the Earth are evident in this piece of work, as he designed it as a way of drawing attention to pollution and other destructive practices.
