Processing is a ‘visual’ programming language based on Java, which is designed for artists, designers and creative hobbyists to make cool, software driven graphics. The program and libraries are freely available, and in the few years that Processing has been around, it’s fostered a strong community who readily share the code behind their creations. The best thing about it is that little or no programming experience is required to get started, and impressive results can be achieved in no time. But add-on libraries which enable MIDI support, and computer vision capabilities make the possibilities almost endless.

**Yikes! I originally embedded a Processing application in this post, but its computationally intensive, so I ditched it. Look at some of the links above in order to view Processing applications on the web. Thanks!**
