Christmas is **just around the corner** and I haven't bought all the gifts for my family yet ( yeah, đ˘)
My Dad has a PhD in Mathematics, he works in Graph theory and his thesis was about Quasiperiodic tilings.
What do you think would make a good gift for him?
I'll appreciate anything you could think of!
Thanks for reading, hope you have a great day đ.

p.s.: after reading all the tags in this website I think this is the right one for this kind of question? please correct me if I'm wrong!

notgetting your dad a math-related gift? Maybe I am not "mathy" enough but I usually find such gifts a bit boring/easily forgotten (ok, I love the suggestion below about Hagaromo chalk!) $\endgroup$14more comments
