-. If you are interested in magnetic symmetry, I recommend consulting the downloadable files produced by Danny Litvin at [http://www.bk.psu.edu/faculty/litvin/Download.html]. You can download a complete set of "International Tables" specific to magnetic space groups.
+. The online program ISODISTORT [http://stokes.byu.edu/iso/isodistort.html]is extremely useful if you are interested in phase transitions between group-subgroup related phases of a crystal. It includes an excellent Java applet to display the relevant distortion modes.

-. I strongly recommend the following e-crystallography course. It covers a huge range of topics and has some excellent Java applets that can be downloaded. In particular see the applets for making an Escher type pattern, for diffraction geometry and the wonderful charge-flipping applet. In the last one you can draw a molecule or collection of atoms,calculate the diffraction pattern and then allow the charge flipping iteration work back from the intensity data to your original molecule. Magic!

 '''Dynamics'''
-. Two computer programs that I have made available for free to simulate the motion of  monatomic and diatomic chains. The first program is for a 1-dimensional chain and the second for a two-dimensional system (the motions are mind-boggling!). I discovered while writing these programs that there is a diagram showing acoustic and optic mode displacements that appears in almost all solid state textbooks: unfortunately this diagram is incorrect.[http://www.amg122.com/programs/page3.html]

 . A free computer program called VIBRATE! to compute the irreducible representations for vibrational modes. Useful especially for Raman spectroscopy.
