Wheels within wheels

Interior architectural detail at the National Museum of the American Indian in Washington, DC.  Quoting from the museum's website:

The building’s distinctive curvilinear form, evoking a wind-sculpted rock formation...form[ed]  the basis for the architecture. Following this conceptual design work, the project was further developed by [Johnpaul] Jones, [Donna] House, and [Ramona] Sakiestewa, along with the architecture firms Jones & Jones [link and PDF details], SmithGroup [link and details] in collaboration with Lou Weller (Caddo) and the Native American Design Collaborative, and Polshek Partnership Architects. This extended collaboration resulted in a building and site rich with imagery, connections to the earth, and layers of meaning. The building is aligned perfectly to the cardinal directions and the center point of the Capitol dome, and filled with details, colors, and textures that reflect the Native universe.
