Perec

`There are pictures because there are walls. We have to be able to forget there are walls, and have found no better way to do that than pictures. Pictures efface walls. But walls kill pictures. So we need continually to be changing, either the wall or the picture, to be forever putting other pictures up on the walls, or else constantly moving the pictures from one wall to another.' - Georges Perec, Species of Spaces, trans. by John Sturrock.
