Which constructor to buy in order to visually show the git tree?

Question

git

Looking for a constructor like this https://www.youtube.com/watch?v=1ffBJ4sVUb4&t=4410 for a similar event.
If someone can identify the designer from this video, it will be generally fine.

Answer 1

An interesting question :)
In any case, I'll have to "finish", but here's what I remembered right off the bat:
Kugeli
ZomeTool
Magic Beads
I won't tell you where to buy them - you can find them yourself if you wish (the same Amazon),
well, the last option :)
Good luck, cool if you write later an article on Habré, how the tutorial was made and whether it helped :)
