WHAT IS IT?

This a simple 2-D cellular automaton which represents decentralized self-organization. This is simplified version of Vote model. However behind simplicity this is able to produce complex pattern. During runing the model the red patches concentrated into a labirynth which will appear on the screen.

HOW IT WORKS

First, the system will setup itself into random distribution of red and blue patches. The rules of running are next:
If a patch is red and it has lesser than 4 blue patches this will be blue patch.
If a patch is blue and it has 4 red patches it will be red patch.

HOW TO USE IT

Push the SETUP button you can initialize the system with different density of red and blue patches. DENSITY slider chose a density value from 0 to 5 values.
GO button starts the system.

THINGS TO NOTICE

Decentralization is important simulation of Logo models (see M. Resnick). It is general phenomenon of Universe that very simple systems are able to produce organized patterns from random distribution. Philosophically we can said that the order appears from chaos/disorder. This is a injury of second thermodinamical law.
