The Computer and the Enigma of Leonardo (1975)

The film discusses the history of cybernetics: from first huge and awkward machines, which scientists were trying to design and make them think, see and converse, to mankind's everlasting journey of learning and longing to create a being in its image and likeness, to breath a living soul into it. A parallel story-line talks about the computing power of these machines that were able to detect Leonardo da Vinci's figure among the characters of his own paintings.
