This four-sided pyramid has an arched doorway leading into an interior cavity in the form of a cone. Three windows, created by a pipe with rounded caps, provide light from each direction and introduce shifting shadows throughout the day. Contrary to the angular exterior pyramid, the interior is almost entirely rounded.
This elevation view of the front of the pyramid shows the arched doorway and the rounded window opening on the parallel wall. The dashed lines show the walls of the interior cone as well as the window ledges and openings.
This section cut of the pyramid shows two windows as well as the shadows they create on the wall of the cone and the floor.
