I’m not exactly sure what stream of thoughts lead to this idea. I had been looking for an interesting way to use optics or lenses on a ring or necklace. Days of searching early thoughts lead me to other ideas and still other ideas. I tested various lenses I had lying around trying to make something cool happen until I gave up and decided to create something that works with natural optics. A pinhole camera requires only an aperture (pinhole) and light. I found an old cheap pocket watch I had lying around and set to work trying to make everything fit within.
