Lazy Web Request: The Saturn Rings Photo App

I’d ignored the whole “this is what Earth would look like with Saturn’s rings” thing until Jason grabbed this screen of New York from the video.
Roy Prol made the various photos using the lat/long of various cities. With the combination of GPS and orientation data that’s baked in to so many digital photographs, it should be possible to create a filter–I hear the kids call them apps now–that automatically inserts properly positioned Saturn rings into any sky you want. So if somebody would just hop on that, thanks.
