Great example.

Also, a more obscure example that I love is the Barker technique in UML
Class diagrams.  I've only seen it explained once before, in David Hay's
book Data Model Patterns, but it is extremely convincing in explaining how a
human or computer *should* draw a class diagram, and what styles of diagram
layout boost problem domain cognition.  It is only anecdotal, and not a
formal study, but the example is truly amazing.  At the same time, the
passer-by might say, "Well, sure, if you untangle any piece of spaghetti
you'll get an improvement."  But what is neat is that there is a consistent
set of rules Richard Barker (at Oracle) created for drawing these diagrams
to help people better understand database schemas.
