Such artistic renderings of complex technical topics seem a way for the author to complete their own thought process, sifting the subject down to a concise & pleasing expression. Such expressions should be helpful to beginners, but alas require prolific annotations rarely provided. Too often it truly is a great starting point, but requires a daunting amount of trust & buy-in, applied at great length, to get to where the beginner can appreciate the starting point. For example, I've sifted computing theory down to A = {0|1,...} A(x) <= !(A(y)&A(z)) which methinks is very simple & elegant, but is so far removed from a newbie's experience as to be useless to them. I suppose the limerick form could be followed, with some annotation, to implement a basic encryption program. Might make for a good starting point for a very long chapter on the subject.
