I think this latest circle is absolutely exquisite. If it's a fake than it's an extraordinarily elaborate one. It's not a design that requires absolute perfection in terms of symmetry, but it is very close. The little dots at the ends of the wave crests, nice touch! I can't see it being faked.
As for the meaning. All I can come up with is the obvious wave symbols, and the fact that it is divided into 6th segments (densities?) with a central 7th section. 'Dark' and 'light' are balanced or mixed, but light emanates from, or is connected, to the centre.
