I like your pond idea, John! In my location, it would require some moving (the boulders are currently sitting in the courtyard as they were pulled out of the wall of my house when previous owners opened up doorways), but it's a cool idea and gets you thinking.
In less permie related ideas, I keep telling my husband we should just make our own stone circle. He just wants to roll the biggest one up to the road and paint it with the name of the farmstead.
