Matt Jones argues that short looping videos are the real long photographs.
A loop would be a captured action or situation rather than a narrative, where the duration of the loop is set but the loop goes on forever so you can study the layers, the detail, the figure and the ground in the same way you can a photo. A bottled system not a short story. Think about all the tiny clips you've played again and again on the internet just to see one aspect, one moment, act out -- a goal or a dramatic chipmunk. Not stories, but toy moments.
