I also saw this destruction on a very large scale. I had after all just destroyed/altered an entire level of Unreal and its very difficult to not see Unreal and the world around you in exactly the same scale. (Indeed Unreal Tournament is made "life size" to allow architectural visualisations to easily be created in it)

I began looking at examples of "earth art" and created a small experiment using the google maps, of what the positional data from Unreal might look like if reproduced large scale on the ground. Click the image for the experiment.
