I really enjoyed Balmond's previous book, "Informal", so I bought this one right away.
But instead of a inspired engineer sharing his knowledge about complex design, here you can find drawings on photographs of beautiful landscapes (searching for patterns) and his "poetic" thoughts on nature.
I have to say that this book is beautiful and well designed, but is not challenging intellectually like I hoped. If you're interested in architecture, stick to "Informal", way better than this one.
