Jeff studied the big screens. On each, a picture was in motion. One appeared to be moving through a long corridor, lined with seats like a railroad club car. The picture seemed to rush at them from the left wall. When he turned to the right, a similar endless chair-lined corridor moved toward him from that direction.
"Somebody worked hard on this layout," he said to Snader. "What's it for?"
"Time travel," said Snader. "You like?"
"Almost as good as Disneyland. These movies represent the stream of time, I suppose?"
Instead of answering, Snader pointed to the screen. The picture showed a group of people chatting in a fast-moving corridor. As it hurtled toward them, Snader flipped his hand in a genial salute. Two people in the picture waved back.
Ann gasped. "It was just as if they saw us."
"They did," Snader said. "No movie. Time travelers. In fourth dimension. To you, they look like flat picture. To them, we look flat."
