"Rainer Kohlberger's audio-visual compositions are always fierce attacks on the human system of perception. He refrains entirely from all types of representativeness and referentiality, neither camera- nor computer-generated motifs surface in his algorithmic works. However, what binds him in terms of intellectual history with the avant-garde movements of the twentieth century is the constant search for point zero. No motion pictures meet the retina, but instead, impulses and waves of pure light. The extreme light-dark intervals incessantly vary, climaxing in a black-and-white stroboscope storm. Abstract ghost beings become manifest in digital nirvana." (Norbert Pfaffenbichler)
