The Yi Jing

The human world is full of fascinating things. One of them being the 3,000 year old oracle known as 易经 — Yi Jing in the pinyin adopted by the People's Republic of China (I Ching in the old, Wade-Giles romanization).

This intriguing book is full of interrelationships that are often difficult to visualise. Web pages provide a quick and easy tool for exploring interactively what possibilities they might hold. My explorations are posted here because most browsers don't keep state info (cookies) on locally stored pages. Cookies are used throughout so revisiting a page allows you to carry on where you left off last time.

• Hexagram Families by Trigrams provides an interactive way to investigate the relationships between hexagrams. Eight hexagrams (with text) are presented together, the common factor being they all have the same trigram in the same position.
• Hexagram map showing Zhi relationships presents all 64 hexagrams in an unusual layout. Each hexagram is as close to its zhi neighbours as possible. A zhi hexagram is what is formed when just one line is changed.
• Hexagram Toolkit allows the user to explore the results of a divination reading. By giving the primary hexagram and its changing lines, a number of useful relationships are calculated. In particular it can show the line pathways for each changing line.
