Guidelines
The process of developing new stories consists of a cycle between the Engaged and Reflective States
It is inspired on Sharples (1999) cognitive account of writing:

We have developed the hypothesis that, as the difference between the two sets of social norms grows the originality
of the collective narratives developed by the system increases

However, if such a difference keeps on growing the system
will reach a point where agents cannot communicate anymore and therefore they will be incapable of
developing collective narratives

We are interested in identifying and studying the characteristics of this breaking point
Exploring different ways of presenting the plots generated by the
system
MEXICA presents its outputs in three possible ways:
As a sequence of actions
As a more elaborated (predefined) text
As a visual narrative
(How text influence image
How image influence text)
Visual Daydreamer
In the visual narrative , each action is represented by a scene.
This is an example combining illustrations and elaborated
predefined texts
Princess's frame of mind was very volatile and without thinking about it princess charged against jaguar knight
Princess threw some dust in jaguar knight's face. Then, using a dagger princess perforated jaguar knight's chess
Princess got that depress that committed suicide

Objectives
We are interested in the origins of the creative behavior.
• Initially is provided with basic knowledge structures and skills and, through interaction with its environment, it develops automatically novel behaviors
