Symmetry in Patterns, Snow Flakes, and Gems

Man made patterns to paint the walls and floors and even clothes are examples of symmetry of various kinds  

Some patterns which apparently look like a pattern but bear no geometric symmetry, yet their looks are pleasant (Figs. 9.8-9.10). Sometimes an asymmetry can also be as beautiful as that one having the conventional symmetry. 

While introducing Crystal, it has been stated earlier that the word has been derived from Greek word meaning ice or frozen water. 

In fact a snow flake is a tiny crystal of frozen water and is of various beautiful shapes each having sixfold of rotation symmetry and also a mirror plane of S3Tnmetry.
