Processing 1.0 (BETA): "Processing is a programming language and environment built for the media

    arts and design communities. It is created to teach fundamentals of computer 

    programming within a visual context and to serve as a software sketchbook. 

    It is used by students, artists, designers, architects, and researchers 

    for learning, prototyping, and production.

The beta software for Processing 1.0 was released 20 April 2005 and can

    be downloaded here. Bug fixes are being made as 

    we head toward the 1.0 release. Processing is free to download and available 

    for PC, Mac, and Linux. "
