"OK Glass, have taken a picture."

I often wish I had a picture or video of something that just happened. Perhaps Lily does something especially cute, something really improbable happens, or a car passes on the highway driving extremely recklessly. This requires continuous recording, but you can delete the recordings after a short time by default, for privacy reasons and disk space limits. We can't do this yet because of battery life, but I'm looking forward to when we can.
