For some time I had other work to do and could not occupy myself with this blog. Now I am back. Unfortunately, I have great difficulties to understand my own programs that generated all these images. This is not surprising. Usually I am programming rapidly a hack to get results.
I want to do better now and write good programs that explain clearly my methods. Then I will publish the programs in this blog, such that you can use them to do your own experiments.
As one says: „an image is worth more than thousand words“. Similarly, a clearly structured program may be more important than a long explanation. This is the main idea for the following posts.
