The Geodome project has been inactive near 10 years. I sent an e-mail to
the author one week ago about my Python work of Geodome. Geodome is a
complete package for building geodesic dome by Buckminster Fuller.

In late 1960s NASA developed computer program that constructs geodesic
dome for space applications. Joseph D. Clinton released basic dome data
for few writers during 1970s.

The funny or ironic thing was Buckminster Fuller would love to
revolutionize housing industry so that working classes become debt free.
But the government and industry marginalized Buckminster Fuller. A group
of hippies, naturalists built dome houses and then slowly faded away
after Fuller's death.

Geodesic dome is a fine example of simplicity and exploitation of
symmetry in engineering. Hundred pieces have to be manufactured and
carefully assembled as a whole, which is downside of geodesic dome I
discovered.

Edward A. Falk applied ingenious technique to generate complex geodesic
dome which I suspect he could invent it by himself. Usually engineering
software includes technical references but Geodome don't have them.

I invested few hundred hours in Python over the years and wanted to
upgrade my Python skill instead using C language. This created
unexpected license issue that needs to be cleared.

Implementation wise, the Python version is object oriented design
compared to structured one. The original one has OpenGL GUI interface.
Mine has OpenSCAD interface for 3D modeling to generate/manipulate 3D
printing parts.

I hope Edward A. Falk would contact me. If not, I will include the
source code of Geodome as tarball when I release it under new name.
