Here is the same but animated:

And the bottom case, animated:

It is interesting to focus on the surviving spot. We can zoom on this area and see what is going on there. The cells have locked into this stable pattern, involving, apparently, two cells only:

excited = @animate for i ∈ 1:30
           excite()
           plotspace(145, 220, 225, 300)
       end
a configuration by locking two neighbours with a period a+b=30.">Stable-2cells-pattern.gif
