Regarding the ck on infinity page: The Jorge Luis Borges excerpt appears to be taken from his story “The Maker”., and can be found in “The Dreamtigers”, a partial collection of his works.
I don’t know about any kudos, though. I think one responding to ck was expected to know the Borges works, where I just looked up the quote 24 years later. And by this time, Mars has stopped making those, anyhow. :P
The Maker is just a few paragraphs. Worth a read. I’m unsure if the page I linked has the entire story or not, though.
