I was going to ask how your implementation compares to Versor[0] but I see you link from it in your readme. My next question was going to be if there are any license issues, since Versor was for a long time only free for non-commercial use, but I see their github is a bit more recently updated than their home page and mentions it's now under the BSD (yay!). Lastly, are you concerned about the patent on the conformal method? [1] There are a lot of great resources linked in this thread. My memory of the last time I took a dive into GA was that there was a split in the resources for representation -- one side tried to do everything axiomatically and symbolically, the other side had some concrete numbers but it was mysterious how they all worked together. Have you seen a super-basic resource that goes through the same sorts of modeling problems middle school and high school students do when first learning trig and classic geometry?

> Lastly, are you concerned about the patent on the conformal method? I did not know it was patented. My module does not specifically implement the conformal method, though. I did create two nul vectors and I called them no and ni, as in the conformal method, but that's about it. It's very much possible to do conformal geometric algebra with my module, but it's just not nearly as optimized as Versor is. I've tried many times to implement Versor in Perl 6, but for various reasons I never succeeded. It's just kind of hard I guess. Also I'm not completely sure the optimization method I implemented is much worse, so it's hard for me to convince myself into doing the effort to improve it. Also, I'm slightly skeptical the method used by Versor is the best that can be done, so again that dissuades me to do the effort. I would love to see it done, though.
