Hi James,
Your many .nod files are very interesting and educational. I've used your HexGrid
information a lot, and the equations that I figured out will be the same, or similar
to many of yours.
For myself, there is still a lot to learn about the Nodes, in order to be able to use them,
so in this winter "reduced workload" period, I'll try to do some documentation about
using some of the Nodes.
