tesseract   The bears are in the forest and the Pope is in Rome
I'm on a beach in Zanzibar or at least I'll be there soon
What a shame to carry with us the residue of fools
Instead of better wisdom and advanced tools

Yi Tools

The Yijing is, itself, a tool to help us understand the patterns in the world. It is a powerful notational system for describing experience. Over the years, in the course of my research, I have developed a number of software tools to help me analyse both the general structure of the symbols of the Yijing, and the structure of individual readings. In the spirit of encouraging a creative, exploratory attitude to working with Change, I would like to make these resources available to the Yijing community on the World Wide Web.

Yi Lattice LogoHexagram Navigator

The Hexagram Navigator brings together all of the structural and algebraic properties of each symbol into a navigable web of pages. Each hexagram has its own page; in addition to links to the other relevant hexagram pages, there are also pages describing the different ways of grouping the symbols. Access the Hexagram Navigator here.

The Symbol Game

I'm working on a game using the symbols of the Yi as the tokens of the game to be played out on a grid. It can be played as a solitaire or, more fun, with other players. I think it's a good way to explore the meaning connections between the symbols. There's still a fair bit to do, but you can find an alpha version of the game here.

SWI PrologProlog YiTool Libraries

SWI PrologThe most useful tools, from my personal perspective, are the collection of Prolog libraries. These provide an extensive collection of predicates and relations that can be applied to generate and analyse groups of gua.

To use these libraries will require some knowledge of how Prolog works and a Prolog interpreter. I developed these libraries using the excellent free interpreter from SWI, which can be downloaded from their web site.
