This is really cool. ChronoAtlas is an interactive atlas of world history. http://www.chronoatlas.com/MapViewer.aspx Just click on Globe Viewer (in the top bar) once it loads to 100%
Yes, it is cool. I'm in the Egyptian New Kingdom on the map. I'll have to play with it a little to get it to load completely. Maybe they require a sign up/sign in, which I'll have to try later. Happy New Year!
