Learn computer programming the easy way with Processing, a simple language that lets you use code to create drawings, animation, and interactive graphics. Programming courses usually start with theory, but this book lets you jump right into creative and fun projects. It's ideal for anyone who wants to learn basic programming, and serves as a simple introduction to graphics for people with some programming skills. 

Written by the founders of Processing, this book takes you through the learning process one step at a time to help you grasp core programming concepts. You'll learn how to sketch with code -- creating a program with one a line of code, observing the result, and then adding to it. Join the thousands of hobbyists, students, and professionals who have discovered this free and educational community platform.

• Quickly learn programming basics, from variables to objects
• Understand the fundamentals of computer graphics
• Get acquainted with the Processing software development environment
• Create interactive graphics with easy-to-follow projects
• Use the Arduino open source prototyping platform to control your Processing graphics

About the Authors 
Casey Reas is a professor in the Department of Design Media Arts at UCLA and a graduate of the MIT Media Laboratory. Reas' software has been featured in numerous solo and group exhibitions at museums and galleries in the United States, Europe, and Asia. With Ben Fry, he co-founded Processing in 2001. He is the co-author of Processing: A Programming Handbook for Visual Designers and Artists (2007) and Form+Code in Design, Art, and Architecture (2010). His work is archived at http://www.reas.com. 

Ben Fry has a doctorate from the MIT Media Laboratory and was the 2006-2007 Nierenberg Chair of Design for the Carnegie Mellon School of Design. He worked with Casey Reas to develop Processing, which won a Golden Nica from the Prix Ars Electronica in 2005. Ben's work has received a New Media Fellowship from the Rockefeller Foundation, and been shown at the Museum of Modern Art, Ars Electronica, the 2002 Whitney Biennial, and the 2003 Cooper Hewitt Design Triennial.
