This document provides an overview of Processing, an open-source programming language and environment used for visual design. It discusses Processing's target audience of visual artists with little programming experience. It also notes that hybrid artists both avoid code getting in the way of design but also write sophisticated code to discover new visual pathways. The document then lists basic syntax examples like comments, print functions, and function names. It provides examples of size, color, shape, stroke, and fill functions. Artists' projects are also mentioned. Readers are tasked with exploring Processing and responding to the author's email in preparation for a final project.
