Ian Waelder negotiates the inability to giving orders to the body; making it respond, creating tension, forcing it to do something for which it is not designed. What remains of this experimentation is only a trail, in the objects that are witnesses of this failure, in the structures that condition the action and also precipitate it. Media such as photography, audio or sculpture carry out this experimentation. We take notice when he stops responding, when he collides, complains, he gets up again in an infinite loop. We tune in at the moment in which the movements are replicated until he has control over them.
