Also from Kaplan (http://archive.bridgesmathart.org/2012/bridges2012-133.pdf). 

As usual, mathematicians follow their platonic inclination and give a single picture to illustrate a whole system ("_it_ exists, why would you ever need more than one single picture?"). So here it is, for everyone else.

As usual, this is very unoptimized, even though there are "easy" ways of making it much faster - time is limited, so I stop working at _functional_ and move on to something else.

Hope you enjoy.
