Barnga is what I call a simple yet elegant learning tool. Though the title of this simulation-game suggests that it is a simulation on cultural clashes, one can feel free to define the term "culture" quite broadly. I have used Barnga for years to help groups understand cultural diversity issues, conflict resolution styles, mental models and paradigms, and most recently the human responses to change acceptance. If you are a business/O.D. consultant, H.R. professional or a manager charged with helping a group of people to become more effective, Barnga is likely to be one of the best learning tool you'll ever own!
