This is the definitive reference book for the aspiring paper engineer. The lifeblood of pop-ups is kinetic energy, or the energy resulting from motion. When a card or book is opened, wonderful things happen as a result of that energy. This is the ultimate collection of folds put together for the purpose of learning how to create pop-ups. The only true pop-up art included with the book is on the first page. A very complex white scary monster jumps out to greet you as you read the introduction, a brief history and the glossary of terms. What follows are fourteen pages of samples of a variety of folds and the resulting effects when used in a pop-up environment and the the final two pages contain general instructions about how pop-ups are made.
