The second structure is the Matrix structure. This structure describes media when it follows nonlinear progression through information. The viewer could enter at any point, move in any direction, at any speed, pop in and out at any place. Like the branching structure, this also has its set perimeters. However, the exact path that is followed is up to the user. The user has the option of participating in decision-making that affect the viewing experience of the media. An example of this is Public Secrets, a website that reveals secrets of the justice and the incarceration system within the US for women. There is a set boundary of what users can and can't do while presenting them with different themes and subjects users are able to view. Different users will find themselves taking different paths, using flash cues to guide themselves through the website. This vast selection of paths presents many users with a unique viewing experience (in relation to that of the previous persons). As well, they have the choice to read the excerpts from these women or hear it out loud. This connects to Borges' "The Garden of Forking Paths" where the participant has a variety of choices on how they see a story unfold before them. Each time, they can create a different path.
