Otto Baum combines art and design into a unique practice that is both technical and creative. With a background in textile and surface design and a passion for hand lettering, he usually realises his creative ideas not on paper or canvas, but directly on walls. The central stage of his work is the 3.60 x 4.60 metre practice wall in his studio, which is constantly being repainted and redesigned. At the centre of this is the use of his self-developed ‘Ottotools’ - customised tools, devices and apparatus that combine precision and innovation. From stencils and brushes to complex devices and digital planning tools: The process of creating his works is just as important as the final image. Baum's work makes experimentation and the interplay of technology, ideas and craftsmanship visible - and invites you to experience the creative process up close.
