I Ching Yin-Yang Clock
I love clocks and have collected and created a number of them. One of the side tracks that keeps me from finishing I Ching Meditations in book form is that I recently designed three I Ching clocks that are for sale. If you click on any of the clocks you can buy them at Zazzle in several sizes.
I Ching Meditation Clock
This one was taken directly from the cover of my I Ching Meditations Book.
I Ching Hexagrams Clock
This clock is also available as a poster. The design is published in the book, Magical Mathematics by Persi Diaconis and Ron Graham, Princeton University Press.
