Did you ever want to dig a hole to China

If I dig a very deep hole!

While not entirely ministry tech related, this is a very original and funny use of Google Maps. Some ingenious Brazilian grad student has made a scrip that will show you where your "hole to China" would end up on the globe. So far I keep hitting water. The cool thing about this, and other similar programs, it that is shows the potential for Google Maps.

For the church, it would be great to see a Google Maps script that shows population densities, Christian churches, or missionary presence.
It reminds me of Romans 15:20

"It has always been my ambition to preach the gospel where Christ was not known, so that I would not be building on someone else's foundation."

How Awesome would it be if we could see the concentration (or lack thereof) of Christian ministry presence. This could really help missionaries churches and agencies determine where the most strategic locations to place their teams.
