How about it we took the concept further, were truly innovative and extended
the concept to 3d.
My precise references is http://www.python.org/sigs/edu-sig/ wherein is
Dynamic geometry software in the tradition of Texas Instruments' Cabri
Geometry II(TM) and The Geometer's Sketchpad from Key Curriculum Press, but
extended to 3D - written in Python using the PyOpenGL and NumPy extensions.

I keep vowing to myself to stay off the list, but this is too frustrating to
Withdrawn from the market do to lack of interest - for reasons I never
And then the concept mentioned on a EDU-SIG wishlist of things that sound
great and nobody will every actually do - except that this one has actually
been started in a significant way. Too frustrating.
Actually have redone it as web-enabled Java. Cool stuff in my humble
estimation for anybody interested in geometry, integrated with exposure to
programming - the code is simple and explorable. The analytic geometry
behind the code sometimes gets a bit hairy - but the link between analytic
and synthetic geometry is now made direct and concrete through the code.
Something only accomplishable through an
opensource approach - which is why the approach leaves the commercial
efforts in the dust, as a pedagogical tool.
Don't know how to generate interest, though.
Certainly never accomplished it here.
