A friend's more updated iphone takes pictures that are an odd combination of three-d and video, while not being quite either. It seems like you are seeing a 3D object when you move your view if the picture, kind of like the online 3D map. Different technologies than old style 3D, I assume?
It would be cool to have a Viewmaster disc of familiar people and things. I can imagine some of the crazy brides I encounter wanting Wedding pics done up that way! Have photo fun anyhow,
