Generative art, a relatively new form of art, is the art of the algorithm where an artist must carefully design the nature of their art work and then instruct a computer to implement the vision. It is an important transformational art technology, well-positioned to inform the expressive realm of artificial intelligence. J.R. Parker's book Generative Art: Algorithms as Artistic Tool presents generative art principles, and ¿Processing¿ sketchbook programming lessons in the same book. It presents a way to create generative art by combining the use of creative coding with art and design best practices. Readers have access to code used in the book through the book's web site at genart.ca, and video podcasts tutorials are also available for each chapter at durvile.com.
