Out of curiosity, is any of you familiar with the book of ancient lore called "I ching"? Did you find it interesting? I became aware of the existance of this book through Dick's "The man in the high Castle" and then I got a copy; I heard that some writers use it to create the plotline, but I ignore how the exagrams can be used in that way.
I'm familiar with it, and would never use it as a substitute for dice. Using a hexagram for a randomly directed meditation Is more my style, and the I Ching is fascinating in that regard.
