Brickville is the closest thing to a Lego SimCity. Imagine if EA Games made a Lego themed version of SimCity. It would look like this. This micro scale city in completely modular. Usually these type of projects can look too artificial, sometimes being too constrained to a set of rules. Brickville seems to have found a way past this problem. This little city is currently 67 or so baseplates in size and is expanding. Not only is Brickville extremely photogenic from overhead, but its profile looks almost real. The variety of the high-rises and skyscrapers help lend the project a sense of realism.
Brickville recently made an appearance at a KLUG show. Where it was photographed by Luap31 and Jameson42. You can find more details over on Flickr: http://www.flickr.com/photos/brickville/10946567563/
