In this still from a video the mules are interacting with porcelain spheres. The round porcelain forms were slip cast as perfect spheres, then, while still soft and wet, were taken to the mules' field. The mules investigated, sniffed and pushed the spheres, distorting and leaving their marks. I cast more of the spheres and took them to the field but this time I pushed and distorted them. Half of these spheres were made by the mules, and half were made by me.
