Julian Jauk contributed to the realization of an art project by Christoph Weber, currently on exhibit at Viennabiennale for Change 2021. Jauk provided a 3D scan of the original object, balanced the ingredients of the printing material - recycled paper, clay and limestone - and finally printed the object, which can be seen on the photo and at MAK Vienna until Ocotber 3rd.
