Created as a collaboration between Prokop Bartoníček and Benjamin Maus, Jller is part of an their ongoing research in the field of industrial automation and historical geology. Installation includes an apparatus, that sorts pebbles from a specific river by their geologic age. The stones were taken from the stream bed of the German river Jller, shortly before it merges with the Danube, close to the city of Ulm. The machine and its performance is the first manifestation of this research.
A set of pebbles are placed on the 2x4, platform of the machine, which automatically analyzes the stones in order to then sort them. The sorting process happens in two steps: Intermediate, pre-sorted patterns are formed first, to make space for the final, ordered alignment of stones, defined by type and age. Starting from an arbitrary set of stones, this process is designed to visually render the inherent history of the river visible.
