Task

A power-grid game is played from a dispatcher's desk above a valley at night, and up close the valley is still a blockout. The agent makes it real: rigged, animated line workers; street lamps with warm bulbs that light the street and go dark with the supply; varied modelled houses with lit windows and smoking chimneys; rolling hills where the ground was flat; soft smoke that rises and drifts from the chimneys and the power station's stacks; and vehicles that never pass through a building. Everything that works today keeps working.
