  We present an algorithm for converting an indoor spherical panorama into a
photograph with a simulated overhead view. The resulting image will have an
extremely wide field of view covering up to 4{\pi} steradians of the spherical
panorama. We argue that our method complements the stereographic projection
commonly used in the "little planet" effect. The stereographic projection works
well in creating little planets of outdoor scenes; whereas our method is a
well-suited counterpart for indoor scenes. The main innovation of our method is
the introduction of a novel azimuthal map projection that can smoothly blend
between the stereographic projection and the Lambert azimuthal equal-area
projection. Our projection has an adjustable parameter that allows one to
control and compromise between distortions in shape and distortions in size
within the projected panorama. This extra control parameter gives our
projection the ability to produce superior results over the stereographic
projection.
