Conway's game of life and the ecosystem represented by Uexküll's concept of Umwelt
Inspired by a mathematical ecology of thearre (M. Dinu) and the eco-grammar systems (E. Csuhaj-Varju et al.), this paper gives a brief analysis of simple cellular automata games in order to demonstrate their primary semiotic features. In particular, the behaviour of configurations in Conway's game of life is compared to several general features of Uexküll's concept of Umwelt. It is concluded that ecological processes have a fundamental semiotic dimension.
