... DIFFERENTLY
Even though they look like the work of extraterrestrials, these circular shapes are purely human in origin. After more than two years of planning and 15 days of hands-on work, American artist Jim Denevan and three colleagues created this spectacular piece of art in the desert sands of Black Rock, Nevada. The artists built up the giant circles using a roll of chain fencing 1.8 metres across pulled around repeatedly by a truck. A circumference of more than 14 kilometres not only guarantees that this work is visible at an altitude of 12,000 metres (as seen on this page), but also makes it the largest sand drawing in the world.
