The Antipodes map

Antipodes Map:

This map helps you find the antipodes (the other side of the world) of any place on Earth.

Drag the left map, by clicking and holding as you move it, and when you will find the desired location, just click on it, and our “man” will dig a tunnel from selected location, right through the center of the Earth, up to the other side of the world which will be represented on Right Map.

This is pretty cool but, for the majority of us, our opposite point will be in an ocean.
