Diagrams, so miracle to signify things and predict changes, are the result of the astronomical phenomena and geographical environment which Fuxi observed in the ancient time. The format of sixty-four diagrams has been set up for three thousand years and that of the eight trigrams for five thousand years. Since then, few tried to change it and most people, especially those diviners, followed the fixed rule to make it as a practice of fortune-telling. When approaching the I-Ching hexagrams for the first time, the author had a very different feel for the diagrams and thought they were just like abstract painting with certain principles consisting in permutations and combinations of yin yao and yang yao. Six yaos from the bottom-up order are respectively the first yao, the second yao, the third yao, the fourth yao, the fifth yao and the top yao, which are all composed of either yin or yang. With the sixth power of two elements, it makes sixty-four diagrams in total. Around half a year ago, an idea came to my mind that I wanted to change the images of diagrams. I thought that six yaos shared similarity with the clock in the time sequence, and thus determined that the round shape of pizza could be cut into six pieces with the first piece serving as the first yao, the second one as the second yao until the sixth one as the top yao. In this case, I-Ching hexagrams could be presented by a roundel composed of six-pieces, as shown in Table Two, with the front as yang yao and the back as ying yao. After this change, I found the original design of the diagrams was based on the solid line or dashed line in one dimension. What would it look like if Fuxi expressed the concept of yin and yang in two dimensions? I thus assumed myself as Fuxi and conceived a brand new two-dimension quadrate of I-Ching hexagrams. From Table Three, the solid line presents yang and the dashed line ying. The outward three rings are called outer diagrams and the inward three rings inner diagrams. The outer diagrams inlaid with the inner diagrams makes six diagrams, which is the most fundamental presentation for two dimensions.
