Motion/Image/Langacker/Gärdenfors: (Langacker, 1987, Reprint 1999 p. 311): how can motion be shown in a picture? In Langacker's example by two lines: a) for a figure that points at an obstacle - this obstacle is mapped three times. b) the three adjacent images of the obstacle are connected by a second line for the time sequence.
If this image stands for "rise", it can be easily reinterpreted into a picture for "mountaineer" without changing anything in the image. This transformation can be seen as a change in the focus.
