‘Smart Surface’: Massively Parallel Actuator Array Controlled by NonLinear Medium. 
NonLinear Medium: 
Medium whose behaviour can not be expressed as a linear function of its descriptors is non—linear. Function is linear if it satisfies both to the property of additivity an homogeneity:
1. Additivity:
2. Homogenity: , for all
In this project the nonLinear medium is represented by a Cellular Automata (CA) or by Belousov—Zhabotinsky (BZ) reaction, which create excitation patterns in the governing layer.
The CA model is convenient for indepth investigation of the excitation dynamics with minimal computation costs. The CA is defined as a 2D lattice C of cells indexed by i and j. Each cell can be in one of three states: resting (P), excited (E) and refractory (R). Cells update their states simultaneously and according to certain rules. Rules for different models may vary, for details see papers [1],[2] devoted to this subject. The advantage of the BZ reaction is that it represents the real nonlinear system in a real time. The behaviour of the parallel actuator governed by the BZ reaction is also shown on Simulations page and in paper [3].
