| Early description of an interactive display device for lectures and demonstrations. |
Managing Director Jason Dill, Coordinating Director of the Unity system, is the highest ranking human in the world. He takes orders directly from Vulcan 3, the underground supercomputer that directs all human endeavor.
When asked a question by schoolchildren, however, he steps up to the interactive blackboard.
| Director Dill was unshaken. He stopped in front of the blackboard. Experimentally, he raised his hand and moved it in a figure. White lines traced themselves on the dark surface. He made a few thoughtful motions and the date 1992 traced itself.
"The end of the war," he said. |
