Of course, everything the machine does must be programmed, but because of the computer’s great speed, freedom from error, and vast abilities for assessment and subsequent modification of programs, it appears to us to act unpredictably and to produce the unexpected. In this sense, the computer actively takes over some of the artist’s creative search. It suggests to him syntheses that he may or may not accept. It possesses at least some of the external attributes of creativity.
