For the Enmedio group, the world has become a fence. A large fence made of many other fences. Fences that exclude, fences that lead to clandestinity, exploitation, constant danger, racism. A multitude of control systems classify and order the mobility of people displaced over the surface of this Fence World. Sometimes, it happens that a body does not accept the condition or place that is assigned to it. In such cases there occurs what they call a short-circuit, an interruption in the operation of the Fence World. The experiences of the groups presented here are illustrative examples of these short-circuits, creative actions capable of dealing with the control systems of the Fence World.
