Created by Greek artist Danae Stratou and the DAST art team in the mid-1990s, this earthwork art is called “Desert Breath.” It covers 100,000 square meters in the Egyptian desert near the Red Sea, and took several years to create. At its center was a fairly deep pool of water, and the whole project was designed to slowly erode over time.
