You and a friend are driving home on a college break; you're in the passenger seat. Bored, you gaze into the middle of an empty field. You notice that distant hilltops seem to move slowly in the same direction in which your car is moving; by contrast, mile markers on the side of the highway seem to whiz past you in the opposite direction. The difference in the apparent speed and direction of objects' motion serves as a depth cue called:
