Shadows, movements of bodies, faces that cannot be identified: only the traces of human beings that blur, break down, freeze In place, then dissolve anew on the surface of the Image. These combine with two very differently imagined spaces: the Soft Room and the Operating Room, which allow the user to interact with sometimes minimalist elements of sound and movement. Fragments of images that are fragments of bodies continuously recur. "Installations" is the fourth part of the work: ideas, traces of interactive installations by Simon Biggs that can be explored with the mouse.
