Wolfram has plenty of experts on algebra, calculus, math, and programming,  
but...

I doubt they have many (or any) who can craft a meaningful diagram, chart,  
or presentation like David Park can. He's a genious at that stuff, and he  
has spent years fine-tuning tools to help.

The examples alone are worth the price, but beyond that, David has  
implemented a MUCH simpler paradigm for combining diverse graphical  
elements. The results are native graphics objects in the end, but David's  
code makes building them far easier.
