100 Cool Processing Sketches
100 Cool Processing Sketches
About the Book
This book begins by describing some very simple projects (draw circles and lines) and by explaining how the language works. Each sketch is a little more complex than the one before, and all are based on creating something visually or auditorially interesting. Use the book for fun, or to teach artists, new media students, and even intro programmers.
