When teaching symmetry groups, one needs plenty of examples.  Examples can come from art, architecture, culture, science, and plenty of other places.  As examples, consider [[escherwiki:Celtic Art Exploration]], [[escherwiki:Frieze Patterns Exploration]], [http://nrich.maths.org/public/viewer.php?obj_id=1341 Frieze Patterns in Cast Iron], [http://mathmuse.sci.ibaraki.ac.jp/pattrn/PatternE.html Seventeen Wallpaper Patterns].

Here are some excellent sources of symmetry patterns, mostly free of copyright.  Choose one (or find your own) and develop a worksheet based on it:

* [http://commons.wikimedia.org/wiki/Category:Maori_art Maori rafter patterns].  Two color traditional Maori frieze patterns.
* [http://commons.wikimedia.org/wiki/Kunstformen_der_Natur Artforms of nature].  Plates from [[wikipedia:Ernst Haeckel|Ernst Haeckel]]'s ''Kunstformen der Natur'' (1904)
* [http://digicoll.library.wisc.edu/cgi-bin/DLDecArts/DLDecArts-idx?id=DLDecArts.GramOrnJones The Grammar of Ornament], by [[wikipedia:Owen_Jones_(architect)|Owen Jones]] (1856).  See also [[commons:Category:Grammar_of_Ornament]].
* [http://fr.wikisource.org/wiki/Dictionnaire_raisonné_de_l’architecture_française_du_XIe_au_XVIe_siècle_-_Tome_2%2C_Carrelage Carrelage].  Stonework from the [http://fr.wikisource.org/wiki/Dictionnaire_raisonné_de_l'architecture_française_du_XIe_au_XVIe_siècle Dictionnaire raisonné de l’architecture française du XIe au XVIe siècle], by [[wikipedia:Eugène Viollet-le-Duc|Eugène Viollet-le-Duc]] (1856). Or browse the whole book for insipiration.
* [[Egyptian Wallpaper Patterns]]. Ceiling decorations of tombs. (Images not free of copyright).
