Does the crescent moon have a different orientation in different parts of the world. i.e does it look on its side or upright at different latitudes of the earth.

the orientation of the crescent moon depends on the latitude of the person observing it (the size of the crescent, however, is the same wherever you are). Think about a crescent moon as seen from the Northern hemisphere, and the same Moon as seen from the Southern hemisphere; if we take the people in the Northern hemisphere as "right-side up", then those in the southern hemisphere are "upside-down", since the Earth is spherical. Since the existence of the crescent Moon depends only on the relative locations of the Moon, Earth and Sun (and not on one's location on the Earth), the Moon seen in the Southern hemisphere is upside down when compared to that seen in the Northern hemisphere. This means that if the concave part of the crescent points "left" in North, it will point "right" in the South. Since the transition from a "left" pointing crescent to a "right" pointing one must be smooth, we require that the Moon be a "boat" instead of a crescent at the equator.

Yes, but the difference is slight. The angle change caused by the axis of the earth visa vi the position of the sun is what causes the crescent shape of the face on the moon to change slightly as apposed to dramatically.
It is all about the star and the position and rotation of the left overs from the stars creation. The distant of the star to the earth and moon make the phenomena seen amazing to us with human eyes. It can not be seen and understood without some real investigation on our part. But the amazing effect is instantaneous.

However, I vote for DanE's definition!

I believe if it is a crescent here it will be elsewhere, but the as the angle it is seen at is different, the tips of the crescent are at different angles to earth.

Yes, since the Earth is spherical.

Yes. It looks quite different depending where you are. But the guy above me explained it better than I could!
