Wow, receiving the classification of best post of the year - Thanks much 🙏
Yeah, I just wrote a few of my memories. Many many passed by.
Glad it did similar for you, since this is what this post intends to do. As the community does. More than I ever expected.
Ah the technical thingy: I had to Google, figure out what it was called. I thought just 'math instruments' but then I also though, this isn't just math. Rapidograph it is, sounds and looks really cool as a word.
Owww I have a second part which have to wait till February, since first I want to write a post about something else hahaha
