I wonder how this would go down in a court of law, in that the specific motions they are claiming copyright on were /obfuscated/ or downright /concealed/ from view. I wonder if you can legally be considered to have copied something you have not seen..

I suppose what you'd end up copyrighting is the final effect, not how it's achieved. Which is, I guess, the point.

Without knowledge of the finer points of copyright law (IANAL), is this (the final effect) even copyrightable?
