Hello MSA list! I am hoping to make use of Dexter Perkins' symmetry activity <https://serc.carleton.edu/NAGTWorkshops/mineralogy/activities/lattice_spacegroup.html> using patterns by Francois Brisse, in my Mineralogy class. However, I can't find access to a *color* version of the article. Does anyone have a high-quality, color PDF of this Canadian Mineralogist article they would be willing to share? Brisse, F. (1981) “La symetrie bidimensionnelle et le Canada,” The Canadian Mineralogist, 19, pp. 217–224. Thanks to anyone who can help!

Hi Emily, John Brady (Smith College) has some higher-resolution color versions of Brisse’s diagrams on his course website for minerals - this should take you straight to the PDF with the patterns (scroll down to slide 49): https://www.science.smith.edu/geosciences/min_jb/Lecture_Slides/Crystallography.pdf Enjoy!

Hi Emily, For symmetry in color prints, you might also want to access Peter Buseck’s From 2D to 3D: Escher Drawings - Crystallography, Crystal Chemistry, and Crystal "Defects" which uses a series of Escher prints. PDFs of the prints from the original 1996 Teaching Mineralogy workbook are posted at this site: https://serc.carleton.edu/NAGTWorkshops/mineralogy/activities/25651.html Years ago I was able to purchase most of these prints as sheets of wrapping paper from the Smithsonian Institute National Gallery of Art store. I laminated these and used these as an introduction to 2D symmetry for years. Unfortunately, I didn’t see these listed in the inventory at the National Gallery online store today. However, I did find some of the prints Peter uses such as Butterflies, Fish, on Etsy, but these are only as 8.5 x 11 sheets and may not be large enough to show the overall 2D lattices. Still, try searching Etsy for Escher and the sheet names, e.g.,, https://www.etsy.com/listing/1836027287/mc-escher-fish-design-paper-art-deco?ls=r&external=1&rec_type=ss&ref=pla_similar_listing_top-8&content_source=422c52ea537d06047b1e46867676b234%253Ac55bd812075739dcc4f1b0a5591f57e9972c2049&logging_key=422c52ea537d06047b1e46867676b234%3Ac55bd812075739dcc4f1b0a5591f57e9972c2049 Have fun with these, Dave Mogk Professor of Geology (emeritus) Dept.

Hi Emily, After some searching I found I did have a colour pdf of Brisse 1981. Here's also a slightly cleaned up version of the wallpaper patterns, which I'll put in a google drive link since its' about 15 Mb: https://drive.google.com/file/d/1tw_gJZZHG-HGiNgQYuUF_OEqOuOc49Xm/view?usp=sharing Cheers, Jim Evans On Wed, Sep 10, 2025 at 9:24 AM Emily First via MSA-talk < msa-talk@minlists.org> wrote: > Hello MSA list! > > I am hoping to make use of Dexter Perkins' symmetry activity > <https://serc.carleton.edu/NAGTWorkshops/mineralogy/activities/lattice_spacegroup.html> > using patterns by Francois Brisse, in my Mineralogy class.

Hi Emily and David, I appreciate the shout-out about the 20 x 27 inch Escher prints that I used for teaching mineralogy and that are illustrated in From 2D to 3D: Escher Drawings - Crystallography, Crystal Chemistry, and Crystal "Defects." I’m attaching a PowerPoint that contains a few examples of the drawings. The arrows point to places where there are subtle reverses in orientation without interruption of the overall periodicity. I think of these as analogous to point defects in otherwise perfect crystals. The students need to look carefully to find them. The original prints that I used are still on the wall in the ASU classroom where mineralogy is taught. Tom Sharp uses them regularly but told me that the plexiglass coverings make them hard to photograph. However, I have two pristine Escher Giftwrap books that I would be glad to share if someone is interested in generating the sorts of problem sets that were described in From 2D to 3D: Escher Drawings … Some contain shapes that morph into other shapes. With a little imagination they can be discussed in terms of superstructures and modulated structures. I found them to be lots of fun for both students and instructor. If you write nicely to Tom (he might be angry with me for this offer), he might send you some glary photos. Peter   Other attractive Abrams Books giftwraps for symmetry, if you can find them, are  > On Sep 10, 2025, at 10:53 AM, Mogk, David via MSA-talk <msa-talk@minlists.org> wrote: > > Hi Emily, > > For symmetry in color prints, you might also want to access Peter Buseck’s From 2D to 3D: Escher Drawings - Crystallography, Crystal Chemistry, and Crystal "Defects" which uses a series of Escher prints.
