The Denver Museum of Nature and Science is a fun place to skulk around in, should you ever be in town. Aside from all the great natural history material on display, the building itself has been added on to more times than I can count — leading to some interesting interior architecture.
I made this image in one of the building’s atriums (atria?), that once was a courtyard but since has been closed in and covered with a glass roof. Polished metallic wall tiles lead to interesting reflections and intersecting geometries.
