Muybridge was an English photographer whose work was pioneering in the field of movement.

His work studied the movement of people and animals, going as far as to reconstruct this movement in a device which he called the zooproxiscope, which projected still images from a spinning glass disc to create an illusion of movement. What is interesting is how aware the early practioners were that thier constructs of movement were just that, constructs or recreations, rather than the actual movement itself. The images and the accompanying projections are not just artistic work, but also scientifically show the movement of various species, and area which could not be studied without the equipment used by Muybridge. Particulary of interest to me is the way moving animal is processed into still images, which are assembled into something resembling a circular filmstrip or loop, which then presents us with moving images once again.
