Why should you care about Processing?

1. What is it? 2. How does it work? 3. Why should I care?

Processing is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool. Processing is an alternative to proprietary software tools in the same domain.

(magic happens)

Cool stuff comes out here

Based on Java - Complexity + Big standard library for drawing + Lots of user-contributed libraries for other things

Hello, world (Java) public class Hello { public static void main (String args[]) { System.out.println(quot;Hello, world!quot;); } } > javac Hello.java > java Hello > Hello, world!

Hello, world (Processing) public class Hello { public static void main (String args[]) { System.out.println(quot;Hello, world!quot;); } } > javac Hello.java > java Hello > Hello, world!

Hello, world (Processing)

Philosophy

Philosophy (with lolcats) “Postmodern Philosophy Lulz #04 - Marshall McLuhan & A Cat With Cheese On Its Face”

“What hackers and painters have in common is that they’re both makers. Along with composers, architects, and writers, what hackers and painters are trying to do is make good things.” Paul Graham

“Some artists work in video, some artists work as painters, some artists work with physical materials. “Software is just another medium to work with. You can express yourself and you can communicate through software the same way you can through these more traditional media.” Casey Reas
