Query: Where's the Big Idea? A review in 45 words.

Authored by a repeatedly self-described creative genius, this looks at how new ideas build businesses and how you can use his service marked techniques to do it too. No great ideas, but the section on how to present work is worth the price (when discounted). (45)I'd try "Cracking Creativity" first for great techniques.
