double-sided

I recently had a very vivid dream about a new series of work... Now of course the images are fading, but it was a room full of glass panels, each one with an image on the front and back side so that they could be viewed from either direction, shifting which image was clear and which was blurred. Somewhat like pages of a book, that you could flip back and forth. I'm interested in trying a similar thing in printmaking- maybe on rice paper or vellum?
