Tesseract 2

This particular orthographic projection of a 4 dimensional cube, or 4-cube, also called an 8-cell or a tesseract (see Wikipedia) results in the outer edges forming an irregular rhombic dodecahedron. (The rhombic dodecahedron is not quite regular, as then the struts would all meet in a single point in the center. In this version, the projection angle has been changed so no edges intersect.) The 4-cube is also classified as a regular 4th dimensional polytope, the 4D analog to a cube, and has 16 vertices and 32 edges, and 8 cubic faces.
