I picked these two images at random from a list without really thinking about the psychology. At least for me, this Outside/Inside > unlock/home combination with SciFi futurism really resonates with me more and more over time.
Do you have any similar coordinated Lock/Home screens?

I don't know if this counts but I'm one of those nutters who has no images on either. Just pure black screens.
Come to think of it, maybe they are images. I remember taking a photo with the lens completely covered for something...
