I have put some more thought in explaining the point at infinity in the
projective plane and created a visualization using stereographic
projection onto a sphere[1]. The accompanying article[2] wouldn't
probably be of much interest here, but I am referencing it for the sake
of completeness. I would really appreciate any feedback as I am trying
to finalize the visualization framework (not there yet, but it is way
more polished than two months ago when I dug it out of git repository
after not touching it for about a year).
