The Moon is tidally locked to the Earth. This means it cannot spin around on its axis like a spinning top as the planets do. One side faces towards us and the other side (the dark side – if you want to get all Star Wars) stares off into space never showing us its face.
The following is a video showing what the moon would look like if it actually could turn around. The images were returned by the Lunar Reconnaissance Orbiter (LRO) and then turned into this short movie.
