 A biomorphic spiral-shaped ship's wheel rotated the contents of Marcel Duchamp's "Box in a Valise" where the components were viewed through a peephole.Activated by an invisible electric light beam, a paternoster lift display (resembling a mechanical ferris wheel) rotated small works by Paul Klee in front of the viewer.The Daylight Gallery, so-called because the two front rooms faced picture windows on 57th Street, was a normal rectilinear gallery with white walls.
