I purchased this book because an artist friend of mine was using the term "dynamic symmetry" while evaluating my paintings for an art exhibit in Colorado. He concluded that my paintings were of outstanding quality, as he could see that I had used "dynamic symmetry" in all my compositions. I did not know that term, so I guess this is something I have done intuitively for many years without even realizing it. An artist friend and mentor of his was very much into this concept for his own paintings, and would "mark" his surface before beginning any drawings or applying the first stroke of paint to a canvas. Even though I have a degree in Art Education, I have never heard anyone use this term before, so I did a search and found this book. I am also very much into detail, so, fortunately, the book offers great explanation and disgrams of all the different types of symmetry that can be seen in both the natural and creative worlds. I find this book to be highly intriguing, yet very technical, so find a quiet place and be prepared to apply a great deal of concentration while reading it. I am still in the process of reading this book. I may try to "conscientiously" apply this "dynamic symmetry" to some of my artwork, once I get it all figured out, though I prefer painting intuitively. I hope this newfound knowledge will not cause me to be overly analytical when creating my own artwork or enjoying other artists' creations, but the book truly is fascinating. P.S. Break out your straight edge and compass. Doing a little drawing will help you understand these concepts more easily.
