How do you illustrate your books?
What tools do you recommend for illustrating a technical book on basic programming (Yes there are over 2^100 already but mine will be hard to miss :P). I am considering some master art works of arrays, and other data structures that appear drawn by the master artists. There was a link posted on HN this year if not this month. I really regret not bookmarking it.
I haven't personally written any books, but I have seen this blog article [1] written by Bob Nystrom. He talks about creating his book (about writing an interpreter) in general, but there is a part dedicated to explaining how he illustrated the book by hand and scanned the pictures to include them in the book.
Maybe such a low-tech solution will suit you.
