Around 15:30 in this video she talks about it, and there’s a slide showing other symbols that may or may not be from the same book.

Interesting. The left side of the slide at 15:43 in the video is definitely from page 27 of Symbol Sourcebook, but the detail of the ⌘ symbol doesn’t seem to be: not only could I not find the symbol, but also its caption (“FEATURE”) is set in Helvetica rather than Univers as used in the book.

I have a suspicion that she may no longer possess or even remember the book in question. Heaven knows I wouldn’t were I her, but my memory is atrocious.
