The long backwards tracking shot through a trench in Kubrick's WWI drama "Paths of Glory", which follows the general as he paces along the line of soldiers and his repeated questions, are reduced to their pure geometry in Dietmar Offenhuber's study: Nothing is visible other than various accumulations of points, a line on the ground on which the "spent" frames are counted off in units of 50, and the camera's movement, though the original sound can be heard.
