o.T. (varitiation #3) live recording analog video feedback, Fractal Tree
o.T. (variation #3) is a composition of auto-generated abstract moving images. The moving structures are created with video feedback, a process that starts and continues by pointing a video camera at a playback monitor, causing the picture signal to cycle in an endlessly repeating loop. This phenomenon as old as the medium of video itself, can be considered as an inherent attribute. Focusing on this characteristic of the medium, video feedback is possibly the sincerest way to create moving images because in its purest form, feedback represents nothing but itself. It is the “entrance into that very specialized branch of video called image synthesis, in which the images are not records, but creations achieved by manipulating the basic electronic forces at work in video cameras and displays.” (Robert Arn, October 1973)
As in o.T. (variation #3) the feedback process progresses, dynamic abstract forms are auto-generated. During the evolution of these forms, the picture signal is manipulated through a modified video mixer and body movement – placed between the camera and the playback monitor. Slowly the body interacts with the picture signal, and prevents the system descends into chaos by balancing purely electronic forces.
