There's a relatively new Google Maps hack floating around that's titled HYDESim: High Yield Detonation Effects Simulator. Read: "range and strength of effects when dropping a nuclear warhead of X strength on X location."

This entry in Eric Meyer's blog explains its origins and a few other things. It's somewhat scary to think that such a thing could happen, but interesting nonetheless. Such an unfortunate part of the world we live in.

It's kind of neat to think of how Google has brought about such a wide range of unique and inventive web apps with their maps API. They're real pioneers, despite having a few flaws.
