I was right! :)

Everything in the image is orthographic.
I can't imagine any way of creating an orthographic and a perspective image
at the same time with one render and no external files... :)
The background looks like it has perspective, but that's the fake. Things
are only rotated so that they look like that, and the pattern in the floor
is the radial pattern.

I was right first: beat you with about 10h 54m 32 s :))

I was looking for a sign on one of the shadowless cubes where there
would be a break: stupid not to have thought of clipping...
Cleverly done, though :)

Well, obviously you can't have both perspectives in the same render...
I thought perhaps you did perspective and faked the orthographic part so
they'd line up, but your way sounds easier.

Fantastic Image!
I've read the explanations, looked again and again at the picture
and still don't understand all that was done.
I would love to see the .pov code that did this, but understand
completely if you were a bit "possessives" of this. Would you at least
consider a rendering from a different camera angle so those as
dense as I could begin to understand how you are managing such
a deceptive image?
