Stand: 20.12.2013, 10:45 Winter-blooms and retrospective views    Actually, these pictures have originated from programming- mistakes. We can consider programming- mistakes also to be  a type of  coincidence, and Aleatorik plays a big role with the computer-art (and not only there).    In the AQUAL-Classification, I see Aleatorik at the higher levels, perhaps also as autonomous line. In the framework of the integral view, the evolution also comes into the game again and again. Mistakes are the driving factors of the evolution. Sign-language    In the stack-model of abstract machines, a level-model of the communication and the computer science, there is the semiotic level, that appears in many contexts again and again.     The work with signs is seen with AQUAL as an aspect of the line of formation.
