Processing

Processing is a flexible software sketchbook and programming language built for the visual arts and visual literacy communities. Created by Casey Reas and Ben Fry in 2001, Processing extends Java with a simplified syntax and a built-in graphics API that enables artists, designers, and students to create interactive visual programs without the boilerplate of industrial software development.

Processing's pedagogical lineage traces directly to Seymour Papert's Logo and Alan Kay's Dynabook vision. Like those earlier systems, Processing treats programming as a medium for creative expression rather than a tool for engineering production. Its export capabilities — programs can run in a browser, as standalone applications, or on Android devices — preserve the Dynabook ideal of a personal, portable creative environment.

The Processing ecosystem has spawned p5.js, a JavaScript library that brings the Processing philosophy to web-native development, and a generation of creative coding tools that treat the screen as a dynamic canvas. These systems represent a partial realization of the end-user programming ideal: they lower the barrier to computational creation without fully dissolving the boundary between programmer and non-programmer.
