You'd almost need to go with a loose 'media' (MegaPov has 3 types altogether) because
you'd need to see portions
rotating through the 3D structure.  Oh, but does it have to be animatable, media could
turn out to be slow rendering
(did I even have to say that?).

|         roughness 9
|     }
| }normal {waves 0.5 scale 0.01 translate y*-50}}

|
| Any help prior to the 29th (wonder why?) would be appreacieated?
