The array is initialized to random values. - On each iteration, it draws a line to the array position - with the greatest value. It then replaces that location - and the eight neighboring locations with randomly-selected - values. - - The lines are initially random, but over time a chaotic - self-organizing system evolves: areas of the screen which - happen to have lower values are less likely to be updated - to new values, and so the line tends to avoid those areas. - Eventually, the histogram of changes approaches the power- - law curve typical of such systems. - - The simplest documented self-organizing system is the one- - dimensional equivalent of _c_r_i_t_i_c_a_l. - - I heard about this algorithm second-hand: apparently there - was an article in _S_c_i_e_n_t_i_f_i_c _A_m_e_r_i_c_a_n describing it some- - time in 1997. - -OOPPTTIIOONNSS - _c_r_i_t_i_c_a_l accepts the following options: - - --wwiinnddooww Draw on a newly-created window.
