Succulent sink planter

I first used these antique porcelain sinks as a water fountain in the house, but the maintenance and upkeep made me start thinking of my original plan for the sinks, as wall planters (you can see what the fountain did to my walls and floor). So I disconnected the water lines and filled up the sinks with river-rocks, palm soil and planted some succulents and cacti. I'm thinking of making lamps with gro-lights for the plants out of the old copper water lines.
