I remember reading about a physical device someone constructed with mirrors (I think at an early burning man) that gave you the experience of a huge inter ocular distance to get a giant's eye view. I've always wanted to try one (or the opposite to experience a tiny inter ocular distance).
A pair of periscopes laid flat will do it, but it'll really confuse your eyes. I can feel it on these images: the eye muscles are trying to converge on a distance closer than the focusing muscles want to focus on, and I can tell that's a bit weird. That might be an age thing though.
