My focus is on generative art based on algorithms. The programs I
conceive and write result in line drawings, which are executed on
pen-plotters. Random variations on parameter sets “contaminate” the
outcome in a distinct manner. I am not a mathematician, but the
strictness of mathematics, and the inherent structured order of data
often received from a mathematical process seem to become visual in
the drawings. It is difficult to proof this observation objectively,
but in my judgment it is valid.

This is in line with a basic hypothesis I subscribe to: Some kind of
order is a necessary condition for any aesthetic event.

The image fib_14 sd is a randomly selected section from the third row of a program run. It is then digitally manipulated and printed on paper. Although the underlying structure from the overall image is taken as generated from the program, the enlarged detail view together with the manipulations generate an entirely different image. However, it is closely related to the original image.

The drawings are constructed with the numbers 1-1-2-3 from the
Fibonacci sequence. Hence they are mathematically simple, because
this sequence is well known. A line-drawing is generated with a
program (Python), and its parameter settings determine angel,
number of lines in sections, and generation of random parallells.
Section-width increases per line according to the Fibonacci
numbers. The resulting images are digitally enhanced and printed
on paper. The experiments use a mathematically based starting
point, and continue with intuitive judgements. As result, a series
of strong graphic figures is expected, that are related to each
other.

Image fib_13 w shows a typical result of the process: Algorithmic
run, then digital enhancement.
