Google just recently introduced [cached]Cardboard Camera. If you haven't tried it, do, it's amazing. It's the closest I've seen to transporting somewhere back in time to wherever you took the picture. I've used it with friends, parents, even grandparents, and always it is equally amazing to see the delight on their faces when they realise that they can see exactly what I saw when I was there; they can truly feel like they are part of the scene.
