The film Echo was also included in the exhibition Technosophia in Vienna. The title of the work was “Lilith, without the apple”. A snake was constructed, which coiled up around columns of the entrance hall of the Academy of Sciences. The film was projected from some distance onto the snake’s black head by a 16 mm loop projector that was mounted on a black pedestal. This constel- lation acted as the male counterpart to the snake on the Tree of Knowledge amid the forest of columns of the Academy of Sciences.
