This is the third and final instalment of Human Machines. Over three episodes, Gonçalo M. Tavares and Os Espacialistas created ‘imaginary situations’. ‘This simple machine,’ he says, ‘tries to mark the limits of a body’s shadow,’ before adding that ‘Only once does the Shadow Manipulation Machine collapse completely. This is in death. One suddenly loses one’s feet, one’s shadow, and the position of the old circumference of the world.’ This text is thus both strange and very familiar at the same time.
