Newgrange Megalithic Tri-Spirals -- in 1982!

Recently tracing the forms on the Newgrange Megalithic Tri-Spirals, I recalled being bewitched by them before and found...

a few of the pieces I created back in 1982. I drew a more basic impression of the spirals, infected by the rhythm of the spirals, that seemed so natural.
Then I reversed and superimposed the figure to generate many other figures (Click on title above, "Newgrante Megalithic Tri-Spirals -- in 1982!" to see a few of those figures -- It got extreme!)
