The effect is rather like standing in the middle of that large room, where anyone could speak up and share an idea. Everyone is talking; small stories branch off, coalesce pages later. Speakers shade in one another’s stories, offer another angle, disagree passionately. You turn a page, and the same people have their arms linked together at a protest. Shadows start to fall; in squares of gray text, deaths are marked, moments for remembrance. So many people leave the room.
