Just in case you haven't noticed the New! Explore the Wonders of the World with Google link below your search box, I'll mention it now. Wonders of the World allows viewers to explore various sites around the world (virtually, that is). Right now there are 132 sites in 18 countries. Viewers can use the arrow keys to flip through the locations, they can use drop down menus to find sites by location or theme and they can also use the globe at the bottom of the page to click through and to see where all the Wonders of the World are located.
Clicking through to a location will allow you to experience a 360 degree view of the site (don't forget to look at the More Views buttons at the bottom of the image). In addition, viewers can access information about the site, videos and photos. Altogether a great use of technology!
