Indeed, an impossible object is impossible in stereo,
but I not only like impossibilities but also paradoxes :-).

M.C. Escher's impossible drawings indeed are paradoxical, often
because a certain interpretation turns out to be contradicted 
in another part of the scene. In the stereoconversions the 
same contradiction occurs, only more so. It's a matter of 
taste whether you like the square of impossibility or not.
