Abstract: Organizational structures that can be hung from a fixed surface, each organizational structure having a rod that is configured to have a plurality of radii, such that the structure has a first radius that is configured to be coupled to a fixed surface and one or more other radii configured to provide support for one or more items can be hung/draped on and supported by the structure. In further implementations, the organizational structure includes one or more add-on structures and/or other supporting structures or surfaces that add an additional layer, attribute or feature of organization to the overall system.
