[Squeakland] cellular automata

[Kevin Lawrence]

Randy,

My buddy Jeff made a CA with eToys. The hardest part was figuring out 
how to layout the grid (we did it recursively and posted to this list 
about it).

Each cell had different color 'probes' to look at the state of its 
neighbor like this :

      r
      |
    ----
   |    |
g-|    |-b
   |    |
    ----
     |
     y

It would 'look' at its neighbor like is

test  cells' blue sees black
   yes  ....
   no   ....

Credit for the 'probes' idea goes to my buddy Jeff. I would have kept a 
reference to each neighbor, but the probe thing feels more 'etoys friendly'.
