Dear Julio,
Thank you for your encouragement.
In Japanese high schools, only the elements in the upper half of the periodic table are studied in detail, and it seems that there is a bad habit of neglecting the lower half of the PT.
The periodic table represented by a contour map seems to be able to see the entire periodic table impressively as if looking at a topographical map.
Although it was still in the middle of drawing, I turned the contour map, with Rene's lovely place name, into a postcard and handed it to the students. The students were watching as if they were seeing a rare "landscape".
In this way, the contour map of the periodic table suggests that even elements that are not studied in detail have their own individuality and that there is something characteristic hidden in them. I believe that this will have the educational effect of giving a bird's-eye view of the "whole elemental world."
FYI, I found something interesting.
You can handcraft a precise 3D map with the '紙岳('kami take', or paper mountain)' series.
It's in Japanese, but you can understand it with pictures and videos:

What do you think?
Best wishes,
Nagayasu
