Shelving breaks its orthogonal boundaries with Chuck, a flexible shelving system conceived by German designer Natascha Harra-Frischkorn. Instead of parallel racks to hold the texts, Chuck is composed of six 4-mm bands of wood clamped at two fixed ends. The construction, though conceptual simple, yields a beautiful result and models the organic form of a NURBS curve, with a tangible manifestation of control points as the books placed in the shelf. Chuck – a flexible system by both physical and descriptive means – allows books to be placed not just vertically but also wedge in between the strips at various angles, such that grabbing a book from the shelf is like picking a fruit from the tree of knowledge.
