I think the point here, is that the above object is an "impossible" 3D object, but the aim is to try to make it rotate as if it is actually a 3D object. It would be the equivalent of trying to animate a flyaround of "ascending and descending" or "waterfall" (actually that would make a cool, if difficult project)

you'd have to animate a couple of models and keep compositing them.
