[Derec] touched the connector to the stump end of the Supervisor arm, and it clung there as though it belonged... Almost instantly, the disembodied Supervisor arm slowly began to flex. "Look at the joint," Derec demanded. "Tell me what’s happening."

"The changes are taking place more quickly than my scan rate allows me to observe," the robot said. "However, I infer that the dodecahedrons are undergoing some type of directed rearrangement."

"Flowing into a new shape. The material of the arm is transforming itself."

"Those descriptors are imprecise but consistent with my observations. The technical term for such reorganization is morphallaxis."

Derec felt for his chair and sat down shakily. The Supervisors had been built out of billions of tiny crystalshaped modules-a cellular structure. Each had to contain kilometers of circuit connections, megabytes of programming. It was the cells that were the robots. The robots were more like organisms.
