Peter Senge gives an account of how he uses computer simulations in his "The Fifth Discipline: The Art & Practice of The Learning Organisations", Century Business, 1993, ISBN 0 7126 5687 1.

If we are going to find our way through this turbulent time we are going to need an awful lot more play if we are to avoid a hardening of the categories leading to fatal consequences.
