View Your House on an 8-Bit Game Map

The Real Game Map Generator is a clever OpenStreetMap based tool to create an 8-bit game world map from any real world location. Just enter your address into the map and you can create a little game world map of your own neighborhood.

I've no idea how this works. My guess is that the application looks at the color of the underlying OpenStreetMap map tiles and then uses these colors to create the game map. Green colors on OpenStreetMap are likely to be parks, blue is likely to be water and orange will be roads. Presumably the application has a number of set game map tiles which it can then use for each of these features identifies on OpenStreetMap.
