This book is about the relationships and synergies between art and mathematics. Several facets are considered, i.e., art that has a mathematical foundation (e.g., mosaics), mathematics that is applied to art (e.g., perspective) and mathematics that results in things that most would consider pleasing to view (e.g., abstract tessellations and computer generated fractal images). Topics include tessellations, perspective in art, optical illusions, various patterns such as spirals, and fractals. The book has almost 150 illustrations and over 100 references for further study. The required mathematical background for reading this book is minimal (high school algebra and some geometry).
