Sitting here, I'm a little dizzy. I close my eyes to see a hill and a road and a blue sky, and in front of me is someone standing on that road showing me a painting of the same hill, road, blue sky. If I look closely, I'll see a person in the painting holding out a tiny painting of their own showing the hill, road, blue sky.
It's a good trick for stories. Weird when it plays itself out in one's head.
