Time magazine's website has put together an awesome interactive feature that allows you to watch changes in the earth as seen from decades of satellite images. You can click through several preset locations on the Time site.
Best, though, is the "explore the world" feature.
With it, you can type in a location. I typed in "Anniston," which allowed me to see from space the growth and demographic changes in Anniston and Oxford, particularly around Interstate 20 and McClellan.
You can see the building of Veterans Memorial Parkway.
You can see the development of properties along I-20 in Oxford.
You can see how Fort McClellan changed after it closed in 1999.
This thing can suck away lots of time on a Friday morning as you look at locations anywhere on the globe. But, gosh, is it fun -- as well as informative.
