Concrete Gravel Filled Water Feature

I just thought I would throw this water feature in since you never know what folks are going to find interesting. I'm not sure what kind of water feature you would call this other than interesting. It does fill up with water and spill over the edge creating a mossy wet look on the large stone. So technically, it is a garden fountain.

A few plants planted in and around the feature would make it more proportionate to its surroundings.
