Check out the 4-dimensional analogue of the dedocahedron, the hyper-dodecahedron or the 120-cell (or hecatonicosachoron).

The image is a projection of this 4-dimensional object, visualised as a Schlegel diagram. The hyper-dodecahedron is composed of 120 dodecahedra, 720 pentagons, 600 vertices and 1200 edges.

The thinner the line, the further it is away in 4 dimensions.
