The Data Wall is a projection screen (transparent scrim) behind the Reader Recall/Arena Administration. During the musical incisions, the Orchestra of Excited Strings plays and are visible behind the Data Wall.
On the screen are projected 12 windows, one window representing each reading table. When a reading block is activated, the indicator box next to that window turns yellow; when the block is inactive, it remains red. Upon being activated, the Archive File code and title is shown, as well as the name and profession of the reader. When a reader begins to speak at a particular table, the text which is being read is scrolled word by word in real time in the respective window on the data wall. (The scribes in the Arena listen to the readers on headphones, transcribing the spoken word into a computer network)
