YEah ! I love that book. I wish companies paid artists to collaborate with their technical writers to deliver engaging content tutorials in graphic novel format.
I think in terms of memory stimulation --->
text + (color + emotion + narrative) > text
The Greeks could memorize incredibly long speeches because they set up such weird memorization queues with bizarre imagery/stories to trigger passages from one topic to the next. Narrative inside technical documentation could leverage this as well.
