The artist couple Achim Großmann and Silvia Eisele ArsCubis have been working in the building of the historic Scraperfactory in the Hermann Hesse town of Calw in the Black Forest for 10 years. The location of their studio in the countryside directly on the river Nagold does justice to the artists’ deep connection to nature. The eternal river Nagold is also a source of inspiration for the duo. Positive tensions between the two and constant interaction make it difficult to answer the question of who created which artwork.
