Jonathan Harris' "10 x 10" builds its content from RSS feeds. The piece selects the most frequently used words from the major news networks to assemble an hourly "portrait" of our world. This visualization tool represents a type of structure that we will soon see in networked books. The human editor/programmer creates the search and visualization function and the machine then collects, edits, and presents text and images according to criteria built into the program. This type of "book" format depends on granular content that can be "manipulated and reaggregated" by a tool.
