Dissolve away the walls and window of this designer home to show us what's left, a chair for reading, a lamp to stare at (a sort of proto-tv, at least if your eyes are fast enough to catch the subtle changes due to electricity's basic instability), and a staircase (perhaps, since a helix shape, used for reproduction). The staircase spins around an off-center axis.     Sometimes there would be a lamp, or a stairway, for decoration.
