Self-organization is a concept I learned about from a book by
Stuart Kaufman. The idea is
that any systems consisting out of subsystems with a great number of rules that define
interactions between the subsystems will show signs of self-organization. Some systems will
help others, while other systems will slow neighbors. In these kind of environments it is
unavoidable that positive feedback loops will occur. A will help B, B will help C and C will
help A, so the whole system will grow in an ABC pattern.

Archean is an implementation of these ideas in the form of a cellular automatum. The
idea is rather simple. Each cell contains a vector of size 6. The average vector of the
neighbourhood is then calculated and multiplied by a matrix. This result is added to the
vector of the cell. By mapping the six reals to rgb space and filling the matrix with random
numbers, fascinating patterns spring to life.
