This review is for the audiobook, too bad I can no longer add books.
This guy is intense! He has some helpful activities to get you thinking about innovation. Not as advanced as Thinkertoys, but valuable in its own way. He thinks more about inventing a product or service to sell, as opposed to just inventing it. Pretty good material, although the music he uses is upbeat, but a little cheesy. Chapter 17 (the last chapter along with the Nightingale-Conant blurb is repeated once, but a little annoying, then the audiobook ends :-)
