This paper proposes that today's computational and generative arts are the legitimate inheritors of the 20th century traditions of constructivism, systems, conceptual and process art . Often formed from close collaborations between art, science and technology this field of work also exhibits important aspects of contemporary culture and thought including: emergence, non-linearity, hyper-mediation, interaction, networking, self-similarity, self regulation and so on. They are also one historical root of the contemporary science of artificial life .
