Abstract
An inhomogeneous cellular automaton is considered consisting of two two-dimensional planes, one of which contains the transition functions or programs and the other the evolving data. With a two-level hierarchy, basic experiments are performed with quenched and annealed XOR and AND functions. These functions were distributed both at random and with correlations produced by a Glauber algorithm simulating a nearest-neighbor ferromagnet, anti-ferromagnet and spin-glass.
