Actually, these pieces are just temporary.  However, the problem I'm referring
to isn't the outside seam (I do expect to see the transition) but is the seam
that is visible through the semi-transparent object at the junction.  In other
words, you can see the entire face of the cylinder/cone.  It appears, though,
that this problem has rectified itself.  Perhaps I *didn't* have everything set
as I thought I did and later fixed it.  I'm not sure.

I've still got problems with the media, though.  The lower blue hand is outlined
with white artifacts.  This is the only one through which the plane is visible.
I've tried a number of media settings, and nothing seems to fix it.  I'm in the
process of eliminating problems and will post again once I have something better
to show.
