Throughout the book I have included a number of different graphics and forms and they may have been difficult to see in the final print editions.  Please click on the picture or image for each on to download the data if you so desire.  

 

At the bottom of the page, I have also included some links for coffee mugs, mouse pads and posters.

 

Please let me know if I am missing something, or if you would like a link to anything else!
