Lattice of conics by Chaim Goodman-Strauss

These are general conics on the projective plane. A lattice of circles, lying on a plane tangent to the unit sphere has been normalized to lie on the unit projective plane. Regardless of the conics chosen in the original plane, similar images (spherical ellipses) would be derived by this procedure. Note that the circles seem to be in perspective, at least if you only look at a small portion of the image. This is far from coincidental.

How to make it: Mathematica produced GeomView output, rendered by RenderMan.
