Remark

 A fairly good explanation of dealing with media representations in Processing was written by Davide Rocchesso and Pietro Polotti. It discusses representations for images, colors, typographic elements (fonts), and sounds in the Processing language.

Example VII.4

 This example shows how to work with live input from a video camera. It uses the JMyron video capture and computer vision library (the standard video library in Processing gives many problems) and pixelizes the video input. Run the code in your Processing environment, and don't forget to change the size() statement to your camera's resolution.
