The implementation that is currently visible in the GitHub commit history was done over about 3 days, yes. But that does not include the research, planning and architecture work that happened before I started committing the implementation.

I spent roughly 2 weeks researching the domain, figuring out the structure of the tool, planning the architecture and deciding how the different anatomical layers and interactions should work before the repo history you are looking at began.

That's great. It reminds me of Elsevier's full-body anatomy tool which is very cool but requires a license of like $60 dollars per year (probably targeted at doctors and medical students). I hope someone can replicate the essence of it and make such a tool available for free.

This could be a part of Wikipedia.

In this case I applaud the utility of something built in 3 days.

Not the engineering effort behind it.

It still looks great. And very good for understanding whatever it is my dentist is doing with my teeth.
