Michael Paul Smith and his amazing miniature town called Elgin Park
Watch this wonderful National Geographic video about a self-proclaimed recluse named Michael Paul Smith who has built a monument to 1950's Americana using miniatures. He calls it Elgin Park and it is based mostly on memories of Michael's own childhood. Flickr picked up on this amazing piece of art and did a feature on Elgin Park with tons of photos to show.
You can see some photos of this amazing miniature town on Flickr.
