‘Harold Cohen realized this limitation of the available graphics equipment. His approach was to delegate only the job of drawing to the computer, for which he used a plotter, a CRT, or the funny- looking ’turtle’-a remotely controlled drawing vehicle. He colored the resulting line drawings later by hand, thus mixing automatic drawing and human painting styles. He recently published a series of his computer-generated line drawings in ‘The First Artificial Intelligence Coloring Book’ as an invitation to everyone to combine their creative efforts with those of the computer.’ [Dietrich, 1986]
