Instructions:

Initially, the Northern hemisphere is shown on the left and the Southern hemisphere is shown on the right.
Click anywhere on the Northern hemisphere and that point will become the central point on the left.
Or, click anywhere on the Southern hemisphere and that point will become the central point on the right.
