I have always described the Whispering Wall as a means (or organ or instrument) to (re)produce ‘chains of thought’, considering ‘Thinking’ an essential part of the work. To the Czechoslovakian philosopher Vilém Flusser (1920-1991), thinking is a process of words, and ‘Whispering’ a primary articulation of a ‘web of thoughts‘, before spoken or written language *1). That’s beautiful. A Whispering Wall is a Thinking Wall.
