Bob Hanson is rapidly developing the display of 2D and 3D isosurfaces with Jmol, and these are potentially interesting for displaying cavities in inorganic structures, particularly framework structures like zeolites, synroc (hollandite) etc eg: click on "demo" and then on the structure formulae on: http://icsd.ill.fr/icsd/index.php?action=Search&mineral=hollandite then click on "cavities". Switch off the polyhedra and bonds for a clearer view. http://icsd.ill.fr/icsd/index.php?action=Search&mineral=zeolite also looks nice, but takes a few seconds to display (depending on your computer).
I would be interested if people had suggestions about how useful this kind of thing might be, and if they had any suggestions.
