Each Thinkertoy is a specific technique for getting ideas to solve your challenges. Each chapter contains a blueprint that gives precise instructions for using the technique and an explanation of why it works—including anecdotes, stories, and examples of how real heroes used each technique to produce ideas and breakthroughs. I call them heroes because they left behind a mark, a sign, an idea, an enterprise, a product, or a service that reminds us of their innovation.
