This book by Dan Roam is a fascinating read- in several hours he stretched my thinking about how people think and communicate. With a practical bent and witty style, Roam walks through how we digest the world visually and how this understanding can transform communication- from problem solving to boiling down complex ideas. The best part of the book is how Roam models the concept on each page with helpful and inspiring pictures all the way through.
I highly recommend this book to any leader or teacher, and especially anyone addicted to whiteboard like me. I have a notebook full of whiteboard drawings I use when I consult. This book messed with my mind by forcing me to reevaluate each one. Here is an example:
On page 211 of Church Unique, I show the "attunement grid". This tool is designed to help leaders identify four kinds of people in church based on a person's ability to see the vision and their willingness to contribute. Its uses a voyage metaphor yielding the four types as stowaways, passengers, crew, and pirates. I have always drawn this grid with words, but Roam would prefer I use picture. What do you think? 
Abby, my nine year old is a wonderful drawing consultant!
