He surely talks about preparing the "transparency" foils for presenting them using the overhead projectors:
https://en.wikipedia.org/wiki/Transparency_(projection)
"A transparency, also known variously as a viewfoil, foil, or viewgraph"
That's how the presentations were done at that time, using the:
https://en.wikipedia.org/wiki/Overhead_projector
The good side was that you were able to prepare the foils before but then annotate any (i.e. write or draw on it) during the presentation, which had its own dynamic -- it could have been a result of the interaction with your viewers -- like while you were answering some question.
The foils were even used in the very talk you transcribed: https://youtu.be/OW-atKrg0T4?t=1295

One of my favorite details that seems to be frequently overlooked in modern times is the ellipsis on menu items to indicate that further user input is required (see "The Ellipsis Character in Menus" in Chapter 4). Lots of software follows this pattern, but a surprising amount of software _doesn't_!
Apple's guidelines used to make it clear that (a) if the only additional input was a simple confirmation, it shouldn't get an ellipsis, and (b) if the whole point of the menuitem/button was to show a window, then it doesn't need 'more input', so it shouldn't get an ellipsis.
Both of these are violated by the Mac's built-in applications in Mac OS X, which is a shame.
Maybe you looked at other platform HIG? Can you share examples where the guidelines are violated by MacOS built in applications, please? Not saying it's not happening, just curious.
In hindsight kind of ironic given how much light blue/blue is used in 'modern' interfaces.
(And there's a sensible reason for this, too - the "pixel art" style is unique in letting you set a uniform ceiling on high-spatial-frequency content and subtle color changes within a picture, while preserving unbounded choice within these constraints.)
That said, I found it super cool that the icons can scale, right in the file explorer (using the "scroll wheel" type thing on the left side of the window)!! :)

This one [1] is one of my favorites, about the MacOS dock when it was first released.

(Something I always found interesting about this, is Bill Atkinson's suggestion that some of the window related UI was already in place before the PARC visit. Having a look at the polaroids in question, seeing Smalltalk may have been even a distraction, at least in terms of the design language.)
A fascinating read about it here:
“Well, Steve [Jobs]… I think it’s more like we both had this rich neighbour named Xerox and I broke into his house to steal the TV set and found out that you had already stolen it.” - Bill Gates

Reading about Xerox parc is super weird though because it feels like the place was handled the way you expect a publicly funded place to be, being so open to share their finding with competitors and all. Truly a golden era, today those are much more closed, even places like MS Research.
