The funnel is created through the repeated application of a scaling function changing its direction upon a triangle function. By reflection and addition of a tapered "stick", a composition is created that describes an artificial object with a minimum of technical devices. The prerequisite for such a computer graphic is the ability to make custom software tools if the used software package does not contain the required electronic tools. (N. Speicher)

Technical background:

All three works were realized on an IBM AT 03 with a Mirage Programme. Through self-designed command files, rotation, scaling etc were realized. The shot was taken with a Matrix-PCR-camera.

Norbert Speicher, born 1945 in Luxemburg, living and working in Munich. After graduation from High School in Luxemburg (1964), he studied at Munich Technical University. 1970 graduation (Machine Engineering B.Eng.). Already during his studies, Norbert Speicher showed interest in computers. In 1970 he started his professional carreer as system analyst with Siemens in Munich. Various job experiences as systems planner, market researcher and editor. Since 1977 independent as marketing consultant, text author and graphics designer. 1980 first pixel graphics experiments with a photo typesetter. Engages himself in the programming of random controlled computer graphics and simple animations. Studies for the realistic design of smooth surfaces by random disturbance of colour brightness. 1986 Foundation of computer graphics company “Laguna Design”. Intensive studies about the stylistic use of the weaknesses of computer graphics for characterizing computer graphics as such.
