this is fun stuff, my uncle did quite a bit of development on micro cameras he worked on and made quite a bit on the patent for the first ingestible pill camera, and had some even smaller cameras for other medical devices that were even smaller (and fun to play with when I've visited a few years back) I also bet many of these lenses can be stacked together to create a nice lightfield display...
