Excerpt from Ray Bradbury's "The Veldt":
"The nursery was silent. It was empty as a jungle glade at hot high noon. The walls were blank and two dimensional. Now, as George and Lydia Hadley stood in the center of the room, the walls began to purr and recede into crystalline distance, it seemed, and presently an African veldt appeared, in three dimensions, on all sides, in color reproduced to the final pebble and bit of straw. The ceiling above them became a deep sky with a hot yellow sun.
George Hadley felt the perspiration start on his brow. 'Let's get out of this sun,' he said. 'This is a little too real. But I don't see anything wrong.' 'Wait a moment, you'll see,' said his wife. Now the hidden odorophonics began to blow a wind of odor at them; the hot stench of animal flesh, the smell of dust, heated grass, and new-found water. The yellow sun blazed down on the distant trees and the giraffes moved their long necks in silhouettes against the sky."
