Dot of Time

"The guide invited the crowd to imagine that they were looking across a desert at a mountain range on a day that was twinkling bright and clear. They could look at a peak or a bird or a cloud, at a stone right in front of them, or even down into a canyon behind them. But among them was this poor Earthling, and his head was encased in a steel sphere which he could never take off. There was only one eyehole through which he could look, and welded to that eyehole were six feet of pipe... Whatever poor Billy saw through the pipe, he had no choice but to say to himself, 'That's life.'"
- Kurt Vonnegut (Slaughter-House Five)
