If a single rotation cannot be copyright, then how about two rotations? Three? Twenty? All have a defined effect. The whole thing is a mess. I don't dispute the advice not to steal poses - as I said, the ones I released myself were all created from a zero base. But looking at it from the point of view of theory of law (which is cheap and entertaining if one does it in this forum rather than in a courtroom) there are grave philosophical problems in supposing that a few dial settings can be considered a "work" subject to copyright.
