From Dan Roam:
After 18 months of effort on the part of many people (Adrian, Ted, Courtney, Will, Amanda, Mark, Tom, Les, Isabelle, Sophie, Celeste, and everyone who provided feedback along the way -- you know who you are!) I am overjoyed to announce that as of today Unfolding the Napkin: The Hands-On Method for Solving Complex Problems with Simple Pictures is here and available!
If you enjoyed drawing on The Back of the Napkin, I think you'll really enjoy Unfolding it. It's not just the sequel, it's a remarkably different reading, seeing, and drawing experience; a complete do-it-yourself 4-day visual thinking seminar in a book.
