Protozoism
Protozoism - What about a non-linear bookshelf? Protozoism is a rotational moulded structure you can hang to a wall, whose internal cells have different sizes and can accommodate different types of object, not just books. The production system makes sure that the cells have a back surface, so that the movements of the books and objects won't deteriorate the wall beyond. It can be fixed to wall through a metallic structure. Available in a wide range of plain colours.
