Twelve regular 2D pentagons join together nicely in 3D to make a dodecahedron. 120 of those dodecahedra unite in 4D space to form the glorious hyper-dodecahedron!  Dodecaplex is a physical puzzle made from sections of a 3D rendering of the hyper-dodecahedron - projected down into 3D, and split apart into pieces. The challenge is to put it back together, and there are three different solutions 5 or 6 of the pieces can be combined into. The plastic pieces snap into place in a satisfying way, providing hours of higher-dimensional fun! Includes color instructions and a storage pouch. Dodecaplex is based on the mathematics of Saul Schleimer and Henry Segerman.
