I haven't seen that. I have seen a rotating camera of a castle spire with the Z buffer culling backwards. It looked strange as the castle seemed to be rotating the wrong way. I recall the skybox was rendered properly adding to the illusion. Edit: I realize what I saw is a textured version of what you are describing.
