ooh, because you'd need to turn every subsurface on it's own? that'll be way too complicated, true... no, what i thought about would more be like a grid which is overlayed and the surface would then be subdivided according to the grids angle, which would produce weird edge pieces, but that wouldn't be the problem then...
No you wouldn't necessarily have to rotate every sub surface on its own but it really depends on many factors, turning them all at the same rotation angle would be easy or even at different angles wouldn't be too hard depending on the angle pattern, or what you want to achieve.
Im sorry I do not quite understand what you mean further?
