Over the past 13 years sculptor Andrew Rogers, with the help of over 6,700 volunteers, has created 47 structures in 13 different countries.

 

 

The structures are large enough to be seen using Google Earth, which is why Andrew put together a Google Earth tour to show them all off. You can download the tour here and see all of his great works of art. One great feature of the tour is that it is designed to automatically switch to historical imagery when it provides a better view of the art work, showing each piece off in the best possible imagery.
