24-cell stereographic projection, color

This is a stereograophic projection of the 24-cell, or octaplex, into 3-space.  The octaplex is a regular polytope in 4-space, the 4D equivalent of an octahedron. All of the polytope edges are circles in this projection, which preserves angles, but not striaght lines or edge length. This makes the 3D projection a unique sculpture consisting of 12 large circles (4 circles each in 3 perpendicular planes which intersect to form a large outer and a small inner octahedron) and 4 small ones,which intersect at the vertices of a regular cubotachedron. The entire structure has 24 vertices and 96 edges (6 arcs in each of the 16 circles). The colors are a linear gradient from one outer vertex in blue to the opposite one in green.
