Acknowledgments
I would like to thank Su, for not hesitating one second in encouraging and trusting my ability to write this book; for believing in me and motivating me with endless cups of coffee.
Javier de la Rosa, with whom I worked on my first Kivy project—the one that gave birth to the blog post that caught the attention of my publishers.
My technical reviewers, Anaí Arroyo, Javier de la Rosa, Hugo Solís and Andrés Vargas for their time and corrections.
My supervisor, Gabriela Barrantes, who has been a constant source of support and inspiration throughout my academic life.
My family and friends, for whom this book will be a surprise, and who've paid with the time that I didn't have to share with them.
The editorial personnel, for their patience in answering my questions.
Celina, for risking her Android to test my codes for the first time; for her constant motivation, support, and criticism even though I disagree that my Space Invaders look like bunnies and, if so, I still think they are terrifying space bunnies.
