I was thinking a bit in similar direction previously - if I define 
rotate vector in the beginning of the scene, and then use it as argument 
to rotate the thing, then I may probably refresh my school math 
knowledge and use the same vector to create inside one. Haven't tried it 
though, since, obviously, even I can't stop people from rotating objects 
the way they used to, i.e. first having an object, then rotating it, and 
not vs (hm, Alice, just think of rotating object before having one).
