What are the basics of computer programming?

Processing is an open source project initiated by Casey Reas and Benjamin Fry, formerly of the Aesthetics and Computation Group at the MIT Media Lab. It is "a programming language and integrated development environment (IDE) built for the electronic arts and visual design communities", which aims to teach the basics of computer programming in a visual context, and to serve as the foundation for electronic sketchbooks. One of the stated aims of Processing is to act as a tool to get non-programmers started with programming, through the instant gratification of visual feedback. It is a language that builds on the graphical side of the Java programming language, simplifying features and creating a few new ones.
