Created between summer 2020 and spring 2022, during COVID isolation, Marcel Schwittlick’s plotter drawing series Upward Spiral concludes with an online archive and a show. The 144 cylinders, each penned by a custom-built drawing machine performing continuous spiral motions, contain all possible colour combinations of the solid-paint marker brand used. Whereas the archive compiles all the Spirals in a neat calendar view, the Berlin Bark LAB exhibition presents a selection of ten.
