I dropped a piece of doughnut on the floor, and it's covered with ants. Two ants are hauling off a section while a third crawls around on top. A fourth and fifth ant push and pull, stopping the portion's progress for a moment before letting it go again. In spite of this seeming chaos, the work gets done.
