The perceived rules of the development and running of alternative spaces, and where those rules came from, are among the questions answered by the authors of Playing by the Rules: Alternative Thinking/Alternative Spaces. The underlying message in the publication is the importance of critical thinking as well as the need for alternative thinking. Some authors use specific examples of alternative spaces from around the world to demonstrate the varied thinking in organizations; some examine alternative practices in other fields, while other authors present alternatives to the alternative space. We hope this collection of essays will provide some inspiration in your own critical thinking and give you some fresh perspectives. With new essays by: Robert Atkins, Julie Ault, Rene Block, Winslow Burleson, Biljana Ciric, Renaud Ego, Sofija Grandakovska, Boris Groys, Marina Grzinic, Pablo Helguera, Naeem Mohaiemen, Raphael Rubinstein, Irene Tsatsos
