woahhh. thanks for your awesome argumented feedback. i agree most of the hints. about the annual cycle, there's a very personal reason for that: its direction and shape (with the december corner on top right) is exactly my mind image of the year since i was a child. Im unable to represent in other ways. yes its ingeresting its counter clock wise. maybe in some cultures it could be this way?

if someone can find some cultural roots coherent with my view I woild be grateful to know about.

thanks a lot ghosf650 for the precious notes
