Nah, much simpler.
Just a plain game board (1000x1000 cells or such) and 
put/get some 16bits of information in every cell, to 
implement that ant simulation. Or a robot war or a car 
simulator.. :)

Like

   Value = get(Map, X, Y, Bit)

   store(Map, X, Y, Bit, true)



There is no array type in Erlang suitable for random 
access ops?

Perhaps on really has to implement some Bif or talk to 
some C written storage server. :)
