Sen-script is a 4th dimensional 'written' language used to express ideas in both probabilistic and chronological context. Each script is composed of three sections that simultaneously define the internal and external structures required for comprehension. The three sections are as follows: Trees (top), Horizon (center), Roots (bottom). The three sections also correspond to the three chronological states, a.k.a. tenses: Up (future), Center (present), Down (past). Visually the script looks like a highly stylized cross section of an actual tree, seen from both above and below ground. All together these linear growths create a 'forest' of meaning. See example below:
Scripting always beings with the establishment of the horizon, this is critical because the proportions of the trees and roots is highly variable, therefore the horizon cannot simply be placed in the middle of the script space, but rather must be strategically placed to allow for adequate growth of the dominant tense.
Roots are always rendered first, although it is not uncommon to work on both trees and roots at the same time, it is however impossible to render trees before roots. Roots are rendered downward, below the baseline of the horizon. New 'branches' are added when significant events alter the timeline. Formal script requires complete termination of all roots. Informal script is far more flexible and may leave all but the primary roots with loose ends.
After or during the creation of the root structure, trees may be rendered upward, above the baseline. New branches are added wherever significant events are planned, additional sub-branches are placed to show how these events will impact the timeline in different ways. The thickest branches represent the most desirable probabilities. Just like with the roots, the formal script always terminates, the informal will only focus on the most important branches.
Typically the initial reading, known as the 'scan' takes place very quickly. Due to the highly visual and inclusive nature of the script it is very easy to recognize the general idea that is expressed. Paradoxically the fine details contain the bulk of the overall meaning, therefore the deeper reading, known as the 'insight' can take a very long time. Both readings begin at the horizon and spread outward in both directions. A quick reading will only focus on the primary tree and its corresponding roots. A slow reading will involve not only all the trees and roots as they are depicted directly, but also the more abstract patterns that emerge within the 'forest'.
This is the written language component of Ku used by neotoy denizens to communicate visually. Since verbal language, telepathy and martial arts are all more effective means of expressing thoughts and emotion, there is not a great deal of sen-script in the city, and when it is used the purpose is most often for aesthetic reasons rather than preserving or promoting ideas. Sen can be described graphically as a series of connected branching lines and geometric arcs which form a kind of tree like structure. There is no set form factor for the text, although there are distinct styles concerning how it is formatted. The most typical is Senso, this is a thin stringy script with no right angles. The more formal variety is called Sensu, and can be distinguished by its characteristic sharp angular segments and thick line width.
