What is this?

A fascinating abstract art work with a pleasing pattern of motifs , ciao Giangiorgio

Well said, Giangiorgio! Thank you very much, my friend! Ciao! PDE

I think this is an abstract fleur de lis, Pierre. To me, the polar coordinates present the opening of the petals in a rather unique way. - - My best always, michael

Thank you very much for your contribution, rather poetic one, Michael! I see something diabolic though! Cheers to that! PDE

Coming from a medical background I might see something “anatomical” in this. But I’d rather take it all in as a beautiful piece of abstract art….masterfully created by you!!!

It is anatomical, Warren! Thank you very much for your visit and shy comment! Cheers! PDE

I see nothing diabolic, PDE. Perhaps Warren is correct.

Yes, I told him he's correct, Michael! Thank you for your reply! Cheers! PDE

Heh! Don't ask me what part of the anatomy I'm looking at. I'll quit while I'm ahead!

Don't worry, Warren, only you and me know that, ha! Cheers! PDE
