Panel Junction combines the graphic novel with forms of shared authorship that have been made possible by the Internet. Contributions from visitors to this site culminate in a free document suitable for printing with an ink-jet printer. It merges spontaneous drawing with scripting and direction from online visitors. Participants from around the world contribute dialog, graphics, caricatures, fonts, narrative ideas, internal monologues, jokes, backgrounds, puns, story-boards, coloring, anecdotes, and sketches. Modeled after the multi-user content management systems used in massively collaborative software development projects, Panel Junction includes narrative "road maps" and different versions of work in progress that range from sketches to refined, high-resolution graphics.
