Subject: Re: [QUIZ] Geodesic Dome Faces (#3)

Your description of the Geodesic face finding algorithm
was quite clear and interesting.  I shall resist the impulse
to toy with it for the time being, keeping in the back of my mind
that this would be perfect grist for the mill of Dykstra's method
of algorithm derivation and simultaneous proof of correctness,
if indeed there is anyone around who still rerembers it
and has mastered the developmental symbology.

I spent some time in the early 1980's reading about Geodesics,
wishing for some sort tools such as you have provided here.

In addition, I am totally new to Ruby (being mainly an experienced
C++ developer with some VBScripting in the past),
and am quite astonished at the remarkable features of this
powerful language.

I shall read on with great interest.

Thanks Again
Tak
