Idea for decorative place in front corner of my fence.

I had to section off the front corner of my fence. Because of living on a hill, most rain storms (or ever power washing my deck) will make water go downhill and dirt collects in that corner. Impossible to keep grass on the hill, and it doesn't help having a dog either. As a result it is now about 5-8 inches higher that the area just back. Do to this lovely hill, we had to add a spur in front of the fence for our third car. Dirt runs through the fence pickets and the driveway always looks dirty. I have dug up the 8 inches of dirt and filled holes from my precious dog. I have in an effort to make it pretty and prevent further dirt buildup, placed the gardening green plastic against the fence, decorative stones and mulched. I have at the moment got black iron fencing about 2.5 feet tall around that, so my dog can not get in the corner and jump the fence or tear it up. Now HELP! I need to find something decorative that will stand outside to place in this corner. Right now there are 4 flower pots with flowers sitting in there. My husband is very pleased with himself for thinking the flowers pots was a good idea. Definitely not attractive. Any ideas of something unique that I can place in there, maybe even something that would produce some light since it is dark on the side of house on the spur. The light would certainly help when my son comes home to park at night.
