Abstract
Shape-changing polyhedra are defined as three-dimensional polygonal and modular structures
that interconnect and change shape and size. Applications include art, architecture, and
engineering. Shape-changing polyhedra are composed of flexibly connected polygons. In their
modular forms they can interconnect, one with another, such that when one shape-changes then
all shape-change. Shape-changing polyhedra can be macro, micro, or nano sized. There may
be thousands of interesting shape-changing polyhedra to discover.
