This is sorta off topic, but the talk of flags reminded me of it.
There is a large portion of land on the outskirts of the downtown core here that was recently purchased by some American developers to create a large seniors complex on the grounds. There was some heated discussion about the land, as it houses many older buildings that at one time were owned by the Crown. The buildings were to be completed and form a Union Jack when seen from the air. There are a series of large buildings that form the thicker lines and some smaller ones, a few of which have been reduced to rubble, to form the thinner lines of the flag.
I just found it interesting that even that long ago, people had a sense to create that third dimension that you wouldn't think they would have. I mean, there would have been no tall building at that time, and virtually no way of seeing them from the air unless you happened to be taken up in a tornado.
Sorry to get off topic, just an interesting tidbit I thought i'd share.
