For a minute there, I thought it was the Dolce & Gabbana logo. :-p
I'm hardly an expert, but that is not the way I understand image maps to
work. It is true that they extend "infinitely" (as close to infinite as
POVray gets, that is) along the z-axis, but they are just applied on
surfaces, since objects are really empty (see 1.4.1.9). You could get the
effect you want by stacking a high number of boxes on top of one another.
But using a heightfield instead would make things a lot simpler, and it
would be a true 3d object.
