Your Unit 2 Project involves design. The dancer in the photograph uses hoops to tell stories through intricate designs. The dancer positions the hoops to display birds and animals, such as the eagle, coyote, grouse, or butterfly. The hoops are circular, often handmade, and range in diameter. When the dancer locks the hoops together, the image created depends on the diameter and areas of the individual hoops.
