Hi James,

Coding a n*n world is actually quite simple.
Just assign the x,y coordinates to your creatures.
Let the creatures do their stuff (you didn't metion how you want this to be 
done!).
Let the creatures move and eat each other.

I once coded such a world for goats, coal, and wolves.
You have to adjust a lot of parameters to make things work, like:
- how close should your predator be to its food before getting it?
- how much food should one creature eat before giving birth to new ones.
- how do the new creatures work? (Should they be like the parent with noise 
on the networkweights? That is: If you use a NN for decisionmaking.)

All these matters give rise to the complexity of such a program, not the x,y 
coordinates assignments to creatures. :-/

Regards and good luck,
