Jller is an apparatus that sorts pebbles from a specific river by geological age. The stones were taken from the stream bed of the German river, Jller. The history, origin, and path of each stone found in a river is specific to its location, as every river has a different composition of rock types. The origin of these stones is precisely documented, as the machine automatically analyses the stones by type and age. The machine works with an image recognition system that processes the images of the stones and maps each of their locations on the platform throughout the ordering process. The information extracted from each stone are dominant colour, colour composition, and histograms of structural features such as lines, layers, patterns, grain and surface texture. It performs this act of sorting with a series of beautiful, choreographed moves.
