Walls | George Perec
'Granted there is a wall, what's going on behind it?' Jean Tardieu
I put a picture up on a wall. Then I forget there is a wall. I no longer know what there is behind this wall, I no longer know there is a wall, I no longer know this wall is a wall, I no longer know what a wall is. I no longer know that in my apartment there are walls, and that if there weren't any walls, there would be no apartment. The wall is no longer what delimits and defines the place where I live, that which separates it from the other places where other people live, it is nothing more than a support for the picture. But I also forget the picture, I no longer look at it, I no longer know how to look at it. I have put the picture on the wall so as to forget there was a wall, but in forgetting the wall, I forget the pIcture, too. 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 picture from one wall to another.
We could write on our walls (as we sometimes write on the fronts of houses, on fences round building sites and on the walls of prisons), but we do it only very rarely.

I am sitting in a room
I am sitting in a room different from the one you are in now. I am recording the sound of my speaking voice and I am going to play it back into the room again and again until the resonant frequencies of the room reinforce themselves so that any semblance of my speech, with perhaps the exception of rhythm, is destroyed. What you will hear, then, are the natural resonant frequencies of the room articulated by speech. I regard this activity not so much as a demonstration of a physical fact, but more as a way to smooth out any irregularities my speech might have.
