Zonohedra and Zonotopes

A zonohedron is a polyhedron in which every face is centrally symmetric. Zonohedra can be defined in various ways, for instance as the Minkowski sums of line segments. The combinatorics of their faces are equivalent to those of line arrangements in the plane. (See my Mathematica Zonotope notebook for details of this equivalence as well as more examples of zonohedra.)
