darn edit time limit didn't let me change out pics to higher res...sorry for the double post and dls...
I have made some advancements on my journey through Vitruvian Man.
Connecting the dots on the Flower of Life from da Vinci's hint of rotation gave me this figure in a 3d model. Convex phi polyhedron All triangle are phi proportional.
From this "phihedron" as I am calling it...I get these projections using da Vinci's drawing as a compass.
Notice in the 2nd that golden rectangles are projected and in line with the background golden spirals layout. I believe this is the detailed map of chakras. In the 3rd pic you see that in this phase the polyhedron can be viewed from 2 perspectives at 90 degrees from one another and project the exact same shape.
I believe that da Vinci was pointing to this object. It may be a lens or some other tool of understanding. Or perhaps something more fundamental.
