Harold Cohen built
AARON, a computer program that allows him to produce paintings.
The initial version was created "about 1972,"
according to Cohen.
Because AARON is not open source, its development came to a
halt when Cohen died in 2016.
In 2014, AARON was still creating fresh photos, and its
functioning was still visible in 2016.
AARON is not an abbreviation.
The name was chosen since it is the first letter of the
alphabet, and Cohen anticipated that he would eventually build further
programs, which he never did.
AARON has various versions during the course of its four
decades of development, each with its own set of capabilities.
Earlier versions could only generate black-and-white line
drawings, while later versions could also paint in color.
Some AARON versions were set up to make abstract paintings,
while others were set up to create scenes with objects and people.
AARON's main goal was to generate not just computer
pictures, but also physical, large-scale images or paintings.
The lines made by AARON, a program written in C at the time,
were traced directly on the wall in Cohen's show at the San Francisco Museum of
Modern Art.
The software was then paired with a machine that had a
robotic arm and could apply paint on canvas in later creative episodes of
AARON.
For example, the version of AARON on display at Boston's
Computer Museum in 1995, which was written in LISP at the time and ran on a
Silicon Graphics computer, generated a file containing a set of instructions.
After then, the file was transmitted to a PC that was
running a C++ program.
This computer was equipped with a robotic arm.
The C++ code processed the commands and controlled the arm's
movement, as well as the dye mixing and application to the canvas.
Cohen's drawing and painting devices were also significant
advancements.
Industrial inkjet printers were employed in subsequent
generations as well.
Because of the colors these new printers could create, Cohen
considered this configuration of AARON to be the most advanced; he thought that
the inkjet was the most important innovation since the industrial revolution
when it came to colors.
While Cohen primarily concentrated on tactile pictures, Ray
Kurzweil built a screensaver version of AARON around the year 2000.
By 2016, Cohen had developed his own version of AARON, which
produced black-and-white pictures that the user could color using a big touch
screen.
"Fingerpainting," he called it.
AARON, according to Cohen, is neither a "totally
independent artist" nor completely creative.
He did feel, however, that AARON demonstrates one
requirement of autonomy: emergence, which Cohen defines as "paintings that
are really shocking and unique." Cohen never got too far into AARON's
philosophical ramifications.
It's easy to infer that AARON's work as a colorist was his
greatest accomplishment, based on the amount of time he devotes to it in
practically all of the interviews conducted with him.
Computational Creativity and Generative Design are two more
terms for the same thing.
