I had the idea to bring mirrors into my landscapes to selectively add and subtract parts of my landscapes recently. A mirror now lives in the trunk of my car waiting, and this past weekend I recently had the opportunity to bring it along on a hike. It's going to take some more brainstorming to figure out exactly what I want to say with it, but here's the start.
I realize this isn't anything new even though I thought I was the first to have this idea (thanks to a quick google search), but I'm going to give this project a go anyways.
