*****  Your description is classic cardboarding. However, the experience of
this circumstance takes place in many ways. As some have mentioned, an
exclamation about the cardboard effect is rather frequent when some persons
see their first stereo images. As such it's a subjective thing, related to
the classic example by way of illustration. It accurately describes what the
newcomer feels they are seeing. Those of us with more experience might
detect a lot more of the smaller parallax factors and include them in the
interpretation and for us it wouldn't be cardboardy... So the term applies
whether the effect is really present as in your example, or just looks that
way for a variety of reasons.
