This simple NodeBox network recreates a famous I Ching circular hexagram chart. The hexagrams are in the Fu Xi sequence, which is a direct binary translation of broken lines (0) and solid lines (1) with bits ordered from the outside in (despite the fact that hexagram lines are normally ordered from the bottom up).

The chart itself is a mere trifle. What interested me was just how easy this was to make in NodeBox - only twelve nodes in the root network with a total of four simple subnetworks. I am attaching a color coded screenshot showing all the subnetworks:

   - Parchment (yellow) creates a simple parchment background with faint wavy lines
   - Hexagram (violet) turns a number from 0 to 63 into the appropriate hexagram. It has 2 subnetworks of its own:
   - Bars (orange) produces, for a given width, a solid line and a grouped broken line with pleasing proportions
   - Hex (green) does a decimal to hex conversion, producing a list of 6 true/false values

I hope this might serve as a simple example for beginning NodeBoxers or as a starting point for anyone wanting to build more elaborate I Ching diagrams.

Enjoy!
