Before we delve into Hyperbole, a number of acknowledgments are in order. Many thanks to Mats Lidell, a long-time Hyperbole user and developer, who maintains Hyperbole with me and with whom I enjoy interacting. Peter Wegner and Morris Moore encouraged the growth of this work. Douglas Engelbart showed us the bigger picture and will forever be an inspiration. His life-long quest at augmenting individual and team capabilities represents a model from which we continue to draw. Chris Nuzum has used Hyperbole since its inception, often demonstrating its power in creative ways. The Koutliner is dedicated to my lovely wife, Kathy.
