I found his Synergetics book (which appears to be as difficult to read as books about solid state physics or differential geometry) at http://www.rwgrayprojects.com/synergetics/synergetics.html
The home page of R.W. Gray, another fan of Buckminister Fuller, and maintainer of the above, is at http://www.rwgrayprojects.com/
He is interested also in Geometric Algebra. According to his choice of adjectives, it is not silver bullet to Science’s Problems and Woes only because there is no such a thing as a silver bullet (at least one with the relevant magical properties).
He links to someone else’s Web page about Geometric Calculus.
