Quite right, blackhearted, I don't know bebop at all, or any of the things you describe. I'm projecting my ideas on him. I said it was only a guess, which means I allow for the possibility it is a wrong guess. Is there any reason why he's picked on you in particular for such a vendetta? The arguments about copyright go beyond idea and actuality. There have been claims here before that hand poses infringe someone else's copyright on hand poses. The idea of a hand pose for a fist and the actual dial settings are almost inseparable. Any two fist poses are likely to be so close as to be indistinguishable. Anyone claiming copyright on a fist is just a public nuisance. As far as I see it, your point rests somewhat on degree. Twisting one dial can't be copyrighted, but twisting 100 can be. How about 50? 25? 12? Suppose I'm working in a theatre working with real lights. I light a scene with 20 spots, should I be able to copyright the arrangement and sue a rival theatre if they come up with something similar? Let's leave copyright for the purposes for which it was intended - protecting genuine works of creativity. And no, I don't see a 3d arrangement of Poser lights as a creative work no matter HOW much work went into it.
