A video projection revolves around the walls in one location, showing a glimpse of another remote location, like a torch sweeping around an imaginary room. Moving back and forth, the projection reveals on the wall progressive sections of a distant space.
Image is locked onto physical fact, a projected fire extinguisher always next to a real coat rack, even as the projection moves past, leaving the memory of a 360-degree space never able to be seen all at once.
Opposite this projection is another, from a camera at the same location, looking into the projection space but also scanning the spaces outside, the image similarly locked onto the physical wall, on the opposite side of the room.
The same arrangement exists in the remote location, reversing the relation of image and object. Two cameras and four projectors in two locations synchronised together.
