The 2D->3D analogy made sense to me -- only being able to see the cross-section that is visible in a current dimensionality -- but I got to wondering if you couldn't use some of techniques from information visualization techniques to show a representation of that extra dimension in the current dimensional landscape (ie fading the object as it gets farther away from the current dimension).
