Yesterday someone asked if I talked about artisanal mathematics here, since I did write artisanal mathematics on my business card. Having never talked about artisanal mathematics, I suppose I should. But then, not knowing what to say, I'll just take Eric Sparling's suggestion to me, so feel free to print out any of the below PDFs and put them in a frame, for your very own piece of artisanal mathematics. Yay for decoration!
All pieces were typed up by me at some point when I was in graduate school. You could even frame a piece of my PhD. You can also ask me for different stuff if you'd like, if you want a one-of-a-kind piece (I'll just pull another random page from my thousands of pages of typed math).
Bonus: the sheets might even contain mistakes! So you could be learning math while enjoying what could questionably be called art.
