Buy this book if you are looking for something in between a coding manual, reference book, discussion of and a history of Generative Art. Matt has hit upon a good balance for those who find a pure programming book makes their eyes glaze over and want to understand the why aswell as the how. The book is structured so that the introduction is gradual without getting too heavy on the coding side of things for too long. After that the book deepens your understanding and teaches you some of the more complex and beautiful algorithms used in GenArt. Not only is it an informative an interesting read in its own right it is also a useful reference to come back to again and again.
