Jller is a machine created by German artist Benjamin Maus and Czech artist Prokop Bartoníček that sorts pebbles from the German river Jller by their geologic age. To do this, Jller first analyzes an image of the stone it selects, extracting information like dominant color, color composition, lines, layers, patterns, grain, and surface texture. The machine then places the stones in alignment of age and type by sucking them into an industrial vacuum gripper and dropping them in the correct […]

Zoltán Sylvester is a research scientist in the field of geology and a world-known sedimentologist, stratigrapher, and modeler. He is a co-PI of the Quantitative Clastics Laboratory (QCL) at the University of Texas at Austin in the United States. Zoltán Sylvester works especially on river meandering over time and how to precisely track how a river – that can sometimes erase its own sedimentary deposits – has moved and changed its path over time. The 3D prints Zoltán Sylvester made so far (with […]
