I’ve been a fan of No Starch Press books for years, and I’m thrilled to have them publish my first book. I’d like to thank everybody there, in particular my editors, Jill Franklin and Annie Choi, for their invaluable feedback and direction. Thanks to Paddy Gaunt, the technical reviewer, for checking over all my code and offering some excellent suggestions to improve it.

Additionally, I’d like to thank the creators, maintainers, and community surrounding Processing and its related projects, and also the developers of the Python programming language. You’ve inspired my students and me, and it’s a privilege to share your hard work with everybody who reads this book.
