I was thinking about time, how on a movie set the shot is maintained in the same time no matter how many takes and hours pass. Reflectors and lights are added, footprints are smoothed away, so that there are no telltale clues as the day wears on. When the shot is finished and the plugs are pulled, time seems to leap forward in a matter of seconds. Perhaps making movies is a step toward being able to move backward and forward and in and out of linear time
