Someone else posted the answer straight from the horse's mouth:

He also appears to reference His Dark Materials, which is my personal favorite book (or trilogy, but they're one work).

There is definitely some His Dark Materials (hey, the new show seems to be doing a decent job of adaptation! I was so nervous) references in there.

Is the wrist scar reference from the series and I've forgotten it or is this from something else?

Hm, the wrist scars don't remind me of anything in particular. He later clarifies that the scars make out the letters HJKL around his wrist - so maybe it's just a gag for that reason.

That is probably right, found this [1] comment where he explains it. I thought the torus/ice stuff was a Jemisin reference!

The style of this series reminds me of the book, "Excercises in Style", which is the same short (2 page) story told in 99 different writing styles!

(Not sure about the style of this individual story)

...which in turn reminds me of Exercises in Programming Style, which I have been meaning to read through: https://github.com/crista/exercises-in-programming-style
