Mecca

For prayer, I wonder how many ways there are to point to Mecca?

Considering that the earth is an eccentric sphere you could start out in any direction in a linear fashion and eventually get there.

The Muslims do have a Quibla compass but that seems a little agricultural for my liking.

Let’s hope there is an app which uses one’s GPS position to give the exact direction of the shortest overland route (post note; there are a few but they give worryingly different answers).
