  Because that's a misuse of the hollow keyword. Also the normals get
inverted.
  It's mostly a preference, but I like to be precise. It's more intuitive
(to me) to define well the inside and the outside of the object. Some
features work differently depending on whether we are inside or outside.
  If I wanted, for example, a media outside the sky sphere (which is
actually the inside of the object), it would be possible. In this case
the sky sphere would have to be inversed and hollow.

  I'm a hopeless perfectionist.

  Btw: Any hope of getting the 'hollow' keyword changed to something better,
like 'allow_media' or 'container' or 'media_container' ?
