This short piece focuses on the world of the theatre, where an astonishing number of human, technical and artistic components may be brought together in splendid harmony without the use of squared paper, computer networks and other common means of communication. Actors learn about the theatre's thousand years of experience and carry with them knowledge of the ancient practice of play-acting: how to reach truth by representation, how to communicate with crowds and individuals, with the individual in the crowd, and with a crowd of individuals. The technologist may see the theatre as a framework of learning from old knowledge and experience.
