viewing crystals with polyedra



 Hello there dear listers,
 I am looking for some nice pictures of crystals being drawn
 with polyedra, like for example silicate clusters drawn with
 bipyramidal polygons having their oxygens at each vertex or
 supracondutor metals.(need just an example for a speech)
 Is there somewhere over the net a ftpsite where I could get
 those images.
 I know Dietrich and Maigret (J. Mol. Graphics, (1991), Vol.9,
 p. 85) have developped a program for visualizing inorganic crystals
 Does someone knows their e-mail? (Iknow this is not the place, sorry)
 Thanx for any help.
 Please do e-mail if possible directly to me.
 Will summarize if there is any interest
 Francois
