#mathober day 31: Existential Closure

There exists an 𝑥 so that

a) 𝑥 is the author of this toot and
b) 𝑥 had a lot of fun with #mathober!

This was a great format to peek into many different branches of mathematics, and also to experiment with digital drawing and #krita!

Thanks to everyone who participated! =)
