Everaldo Coelho used this symbol in Wikipedia as an icon for books about physics.
It looks beautiful, and it is quite fitting, as some of my favorite books (like 'the secret life of plants' and 'hyperspace') are now tagged by my favorite symbol
This is the first time I have seen this symbol being used by anyone else.
He used it first in 2007, one year after I did...
He calls it Katomic, atomic but with a 'K' in front.
Ka means life force to the old Egyptians
It is used in the word Mer Ka Ba.
Also used by Seeds of Sustainability Sprouting Project (another in-synch-link)
and of course my main man Dan Winter:
and by the First Convention on Biological Architecture in Mexico City
at the second one in Wales I am honored to make a presentation and workshop of the Power Flower structure, along with Hero's in this field like Dan Winter and Micheal Rice among others!!!
I have not discovered a precursor to Power Flower's actual materially woven In Phi Knit Knot Meta Structure yet...
(except from protein/DNA strings)
