“Our gaze travels through space and gives us the illusion of relief and distance. That is how we construct a space, with an up and a down, a left and a right, an in front and a behind, a near and a far.
When nothing arrests our gaze, it carries a very long way. But if it meets with nothing, it sees nothing, it sees only what it meets. Space is what arrests our gaze…”
Georges Perec: Species Of Space And Other Pieces. p81.
