Fun. We (your authors) wanted a word to describe our ultimate goal for this book, as well as a word
we hope you (our reader) will use to describe it, and that’s the one we chose. There are others goals,
of course, but in the end, when you’ve finished the book, we’re hoping you’ll have enjoyed the
activities described in these pages.
Many books use the Introduction to explain exactly what the book is about, what the reader will
learn, what the reader needs (a skill or maybe an item or piece of software), and what the reader
will be left with when that last page is completed. And this Introduction will do those things, but …
hopefully it’ll make you excited to get started.
