Text is great, OP. I highly recommend this shrine to the almighty textfile: http://textfiles.com/directory.html

Here's a pile of ancient anime textfiles too: http://www.nt2099.com/OSA/text/misc/

This Maison Ikkoku guide textfile set has always amazed me with the amount of work and care put into it: http://ikkoku.com/mi/html/guide.html From ASCII art of character names in Kanji, to detailed conventions/schemes for information, to all matter of detailed data, this was a real love letter to the textfile.

I think it would also be amazing to use an authentic CRT serial terminal for the Linux console, like this: https://www.youtube.com/watch?v=rh6UJqY1X8U

"If you know the name of a spirit, you have power over it"...Gerald Sussman (your SICP ref reminded me of this).

"The limits of my language are the limits of my world"-Wittgenstein.

Text is the workhorse and meat and potatoes of CS, and old textfiles are a treasure trove of hacking, phreaking, CS, and anime history (along with loads more subjects)
