Interactive Bible maps

Here's a really slick use of the Google Maps application from the ESV Bible Blog: The Bible and Google Maps.

Sometimes we get ideas that are impractical to implement on the ESV website but that might enhance other websites or help people learn more about the Bible.

One such idea is this: why not overlay a Google Map with Bible map data?

Why not indeed? I might have to start working on one of those myself (since they so helpfully share the details of doing so).
