During the congress
AK told me about the
Game of Life
which imho is pretty interresting and makes alot of fun to watch the shapes that will arise in such a cellular automate.
A friend of him implemented a very complex software to do such simmulations in which you can create your own rules etc.
But the basic rules are just that the bit (animal or whatever) will die if less than 2 bits are in the environment because of lonelyness, more than 3 bits because of crowding
and a dead bit will come to life if exactly 3 bits are in the environment.
What I didn't know and I think most of the people don't know is that the famous hacker emblem
is a so-called glider which is just one example of a form of life which can be simulated in the game of life. The glider is special because of its
construction it will glide from one corner to the other.
So here is my small implementation for the glider (you have to edit source if you want to see something else):
