Lania by Anne Fugat - Beautiful! looks like a "nautilus" seashell-the one which grows in a spiral, which has the "Golden Ratio" observable in many places and things in nature. (hint: read up on Pythagorean theorem, chaos theory, repeating digits, etc.
Although I have spent most of my working life in education teaching with a strong emphasis on history, my other love is art, unfortunately I posses no aptitude for art fortunately these artists do! - look, enjoy and learn!
