A puzzle assembly is shown and comprises a multiplicity of geared links
that are arranged such that their turning axes are oriented along the
edges of a polyhedral shape so that when a single link is turned, all
links turn synchronously. In the assembly, there are two end positions of
the geared links. In each end position, a set of link groups are formed,
each of those groups corresponding to one face of the polyhedral shape so
that each link group forms a circular track that is inscribed on that
particular face. When the puzzle assembly is moved to a second end
position, a new set of new link groups is formed corresponding to a
different a different set of faces of the polyhedral shape. The puzzle
assembly further comprises a number of "petal elements" equal to the
number of geared links. The petals have a faceted form and a base piece
that extends from that form for providing a sliding contact with the
geared links. Each petal element is retained by a geared link. When the
puzzle assembly is in one end position, a group of petals corresponding
to a polyhedral face touch each other to form a pyramidal shape. Thus,
one-half of their surfaces are exposed and one-half of their surfaces are
hidden. When the puzzle assembly is "flipped"--the geared links are
turned to their other end position--the petals recombine to hide the
previously visible surfaces and to reveal the previously invisible
surfaces. Importantly, in either end position, the group of petals
corresponding to a polyhedral face may be twisted around the center point
of that face, thereby changing the correspondence between the geared
links and the petal elements.
