Cybernetica - aspects and examples of the science of Cybernetics, some grave, some gay, some beautiful. Three lovely girls converge on Paris exploring as they travel the wonders ot a new age, the new railway age in which computers defeat by the speed of their decision-making the contemporary evils of congestion, pollution and wasted space and time. "We can travel all we want yet leave the land, the air and the sunshine undisturbed." (Produced by British Transport Films on behalf of the Union Internationale de Chemins de Fer)
