The 120-cell is one of the six regular 4-dimensional polytopes, the 4-dimensional analogues of the 3-dimensional polyhedra. This is the result of taking the edges of the polytope, radially projecting them onto the unit 3-sphere in 4-dimensional space, then stereographically projecting the result into our 3-dimensional space. We remove the half of the design in the hemi-3-sphere nearest to the projection point, which makes printing the image in 3-dimensional space feasible.
