![Dynamic geometry via treating transformation functions as moving points with orientation and scale][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=moebiusStrip.png&userId=2991923 [2]:...
In this preliminary post I introduce the idea of dynamical Transformation Functions, that is, the situation where the Transformation Matrices have functions rather than numbers as entries. I apply this specifically in the case of even (direct)...

I have discovered that although this post displays correctly in the web and notebook versions that if one tries to run the entire notebook at once that it does not come out correctly. As I have explained, this method is not designed to be automatic,...
