i like it! It's like a nice Numeric Mini - Tutorial...
so
Numeric.resize(Alien(),(x,y))
gives me an (Numeric) Array for items of type Alien() (class object 
reference) with size x*y ...

aliens[i,j]=Alien()
puts something in it

and
myAlien = aliens[1,1]
gives the reference back to me?

that's teh cool! It's so much easier than i thought, time to rewrite 
some of my stuff... using lists, on the other hand, forces you to think 
about what you do in terms of necessary / unnecessary accesses for speed 
reasons...
