Roger von Oech's Innovative Whack Pack. The Innovative Whack Pack is a card deck consisting of 60 creativity strategies inspired by the ancient Greek philosopher Heraclitus.
Each card in the deck packs a two-sided creative punch. One side has a provocative insight about innovation from Heraclitus, the world's first creativity teacher. These 2,500 year old ideas -- such as "You can't step into the same river twice," and "Dogs bark at what they don't understand" -- will give you a fresh perspective.
The other side contains a creativity strategy inspired by each insight. Roger von Oech enriches these strategies with amusing anecdotes and intriguing questions that will "whack" you out of your habitual thought patterns.
