 Jaccia has the property that, when started from this condition (entire
 maze filled with slime cells), the automaton will eventually reach a
-fixed point (steady state) which contains all possible paths from food
-to food.

 Jacciata is similar, but has the property that when it reaches a fixed
 point, it will contain the *shortest* path from food to food, if such a
 path exists and is unique. If no such path exists, or is not unique, the
 result is undefined. It is otherwise similar to Jaccia.
 
-The behaviour of both automata is also undefined if the slime
-configurations are not orthogonal (that is, if there are any diagonal

 Happy intelligence! Such as it is.
