I think another good idea would be to have a propaganda type video. The whole five minute video could be based around the fascist reign of H I T L E R or some communist leader such as Joseph Stalin. The dictator being the Butcher and the ordinary civilians being the Pigs. I also think some visual images of pigs and butchers could be used to really bring across the metaphor. One of the best influences for the idea came from the following picture which I used as one of the centre peice for my art investigation............ I'm also a young historian which is why I love the whole idea.
