8 While he was studying at the University of developed several academic projects with Python , from web crawlers toartificial intelligence algorithms. In his spare time, he started building his own games inPython. He did a minor in game design at Hogeschool van Amsterdam, where he created asmall 3D game engine based on the ideas he learned during this has also developed some open source projects, such as a Python API for the PhilipsHue personal lighting system. You can find these projects in his GitHub account to this publication, Alejandro collaborated with Packt Publishing as a technicalreviewer on the book Tkinter GUI Application Development would like to thank my parents, Feliciano and Mar a Teresa, for their absolute trust andsupport.

9 They have been an inspiration to me and an Example of hard would also like to thank my girlfriend, Luc a, for her love and for putting up with mewhile I worked on this Howse is a writer, software developer, and business owner from Halifax, NovaScotia, Canada. Computer games and code are imbibed in his earliest memories, as helearned to read and type by playing text adventures with his older brother, Sam, andwatching him write graphics demos in s other Books include OpenCV for Secret Agents, OpenCV Blueprints, AndroidApplication Programming with OpenCV 3, and Learning OpenCV 3 Computer Vision withPython.

10 He works with his cats to make computer vision systems for humans, felines, andother users. Visit to read about some of his latest projects done atNummist Media Corporation dedicate my work to Sam, Jan, Bob, Bunny, and my cats, who have been my lifelongguides and congratulate my coauthor for producing an excellent compendium of classic examples ofgame development. I am grateful for the opportunity to add my chapter on checkers(draughts) and computer am also indebted to the many editors and technical reviewers who have contributed toplanning, polishing, and marketing this book.
