Google Maps 7 Wonders of the World

Juan Taylor has created a cool little mashup project where he takes 7 wonders from various "worlds" and maps them onto a Google Map for all to explore. Each of the maps contains a list with quick-zoom functionality that brings you down to the location so you can take a closer look on a Google satellite map. He provides a way to learn about the locations with short descriptions and the option to link off to a Wikipedia entry for that place, offering more detailed info. Check out some of the maps he has created:
