flower chess board with hidden wallet (Zhen Xian Bao)
Got idea from some pictures shown by Mr. Zhao, the president of Hong Kong Origami Society, who happened to know recently Joan Sallas, a Croatian lived in German and knew an interesting story about the model.
In 1866, a Chinese named as 徐文惠 designed and folded a model used as a sewing kit for containing some needles and thread, etc. and gave it to a French as a present.
And the Croatian knew by Mr. Zhao also showed him some proof files about it.
Think twice, from 1866 to 2016, 150 years went by. And I am proud that early in those days, Chinese can make such an interest model.
However, I made it as a chess with hidden wallet not to put you up to gambling, just for fun, For example, you can leave a note somewhere and let others to find it and do as it asks.
At last, question for whizs, what's the box/pocket distribution and it accords with the distribution of which concept model in computer science.
my one-piece Zhen xian bao has given to John Sallas as a present for his related exhibitions.
Here is some other pictures about it as well as a tutorial:
