In January of 2006, I was trying to come up with a new presentation for a Xerox customer meeting when a series of steps led me to a project that has taken up most of my leisure time and resulted in the publication of nearly twenty new books during the past year. Since embarking on this project, I have had the opportunity to talk about it with many audiences and with my students and colleagues at RIT. As I have
done so the project evolved to the point where I began to feel the need to describe it in a book of its own. But to stay faithful to the spirit of the project, I did not want to spend a year of hard labor writing this book. So what you have in your hands is the product of about six days of work. I hope you enjoy it!
