Some questions. When they brought people in and found they could influence the machines, could they just concentrate on one machine or would they affect any nearby machines? What is the range? Could I influence a machine on the other side of the world? If so, is there a time delay or can I affect the machine before I try to? Could I be shown a rapidly changing series of pictures that would affect the machine rapidly? Could rapidly changing patterns be used to send info across the world without use of radios?
