Someone at the Google Earth Community called ‘maiky1974’ posted a placemark showing a garden in China which has a map of the world 
when viewed from above. Just to the south there are ponds in the shape of China and another in the shape of the province (see comments in the GEC post). The satellite photo of the area has a bluish tinge to it (probably due to haze and lack of color enhancement). If you click on my thumbnail here you will see a larger photo of the area. I color enhanced the photo using Picasa. Thanks to Joe for the tip!
