Heh, that really was a coincidence. Honest!
I must confess I've only briefly leafed through your book at the
library (the motivation to buy beginner's text books disappears after
you've gone through one or two of them), but I always did like the
concept in it of teaching through something more "fun" like
I wonder if a similar "theme" is apropriate for proposed book.
Graphics and sounds give a very direct feedback to the programmer, and
I expect that helps with the motivation.
Perhaps a single largish application could be the "end product" of the
book. Like a game or something. You'd start off with some examples
early on, and then as quickly as possible start working on the low
level utility functions for the game, moving on to more and more
complex things as the book progresses. You'd inevitably have to deal
with things like performance and other "real world" tasks.
It might be difficult to find something which would work well, though.
