Video-Feedback, Music montage from Polyrhythmische Variationen, 1991/2015 


Image feedback creates self-generating dynamic structures. These images show flows and whirls, repetitive and iterative structures. Image feedback comes up, when the camera is pointing at the screen of this monitor; images are created within images, which become unstable when zoomed in and build bizarre shapes. It is most remarkable that in nature with plants, animals and human beings (ferns, snails, ammonites, spines and so on) iteration is a general forming principle und that the artificially (!) generated video-feedback reveals the same principles.
