When walking, if I find a feather I often bend over, pick it up, hold it high and let it loose to watch it spin, twirl, float, flutter, circle or otherwise make its way back to the ground. I love the way each feather shape elicits a different motion and I cannot always predict exactly what it will be. Daniel Wurtzel uses blowing air engineered to do amazing things to different materials including feathers. The feathers he uses here are wing flight feathers, which spin, shafts downward. Body feathers float and circle. Other feathers come down in different ways as air flow interrupts the pull of gravity.
