The void and puddles of colour played a metaphysical role in generating images and associated forms of the frame (as the outer perimeter enclosing the images).

​

I wondered if Nature might provide a scheme as an alternative to the metaphysics. 
        
Years earlier I had admired examples of rhombic tiling composed by the English Physicist. Roger Penrose. I now constructed a ten sided rhombic figure (decagon) comprising ten rhombi and I found that the ten long diagonals formed a fan of radials at 18° intervals over 180°. (Nominate this as CLASS 18°).

​

I further discovered rhombic classes with radials at 15° and 20°. These angle intervals determined the polarity of the rhombi. Each polarity held unique properties. For example, a 15° (CLASS 15° polarity determined the rhombi progress mathematically from just one to infinity. For example, see 'Three Events of Insurrection'.
      
I was able to attribute colours of the spectrum to the various polarities of each rhombic class. Rhombic CLASS 20° resulted in the spherical image, ‘The Spinoza Lily’. And there, in its structure, I could see the rhombic form of the Taijitu, the Tao totem of the Yin/Yang*.

* ENANTIDROMIA;

The Greek sage Heraclitus (Ca 500 BC) suggested that sooner or later everything turns into its opposite.

The Chinese philosophers in the I Ching posited that when things have reached their culmination, they transform into their opposite

​

In ‘The Spinoza Lily: The Seed’ the rhombic construction lines change (from white or black) as they cross the shared border of the Yin and Yang.
