- Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, following state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance).

Fatima Gate, also known as the Good Fence Crossing, is a former border crossing between Lebanon and Israel. On the Lebanese side, it is close to the village of Kfar Kila and on the Israeli side, it is west of Metula. The crossing has been closed since the Israeli withdrawal from Lebanon at the end of the 1982-2000 South Lebanon conflict, and since the summer of 2000 has been the site of many anti-Israeli demonstrations and cross-border stone throwing from Lebanon to Israel.
