Implementing Excursions

The excursions will be crucial to the success of the design. Here I shall try to figure out what they comprise.

eyes down
eyes left
eyes right
eyes up: “Oh, lordy!” 
double eyebrow lift
single eyebrow lift
narrowing eyes
elevated jowls, tightened lips
tilt head, eyes upward

Next I need to set up the relationships between the moods. This will take the form of a table of probabilities for each excursion as a function of each of the three moods:

probability(excursion, sadness_joy, suspiciousness_trust, fear_anger)
