In the atrium of the National Museum of the American Indian, the concentric rings of the upper galleries and the cupola resemble the orbits of planets around the sun or a beehive, and possibly, an exotic wheel cover.
Very fitting, in any event.
Enroute from viewing a magnificent photo exhibition at Pier 24 back to BART recently, my fellow photographers and I cut through the lobby of Spear Tower. Off to one side of the atrium was this towering lattice-like structure. And looking up, was rewarded with this kaleidoscopic image.
