My collection of Dystopian imagery procedes apace, and continues to be added to:
I will start on the Utopian collection as well at some point, but I need to think of appropriate sources to use. There are very few movies and television programs that feature unambiguous utopias, though apparent utopias may also be ok for the purposes of purely visual research.
Even at this stage, there is a clear trend for imagery (facelessness, repetition, maze-like environments) and colours (drab, dark, washed out). More will surely continue to emerge.
