[Rockhounds] Crystal systems templates

[Lawrence Rush]

Don Peck  (the author of the book that Nate recommended) was kind enough to 
send me the following information. Although I won't need it, this looks like 
a super teaching device.......

(This program can be found with Google, and may need some translation into 
English.)

"Have you seen the computer program, Kristall2000?  It allows one to build 
rotatable wire-frame crystal models for any mineral and with as many forms 
as one wishes.  Also, the development of forms may be manipulated to 
increase or decrease the development.  Then there is a feature where the 
crystal model can be printed flat.  It is a great program for teaching 
crystallography.  The learning curve is a little steep and the printed 
models are a bit small (constricted by the size of a sheet of paper).  Never 
the less, it is an impressive and useful program."
