+ The _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl program displays a self-organizing critical
+ system that gradually emerges from chaos.
+
+ _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl performs a simulation on a two-dimensional array
+ of integers. 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 _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl.
+
+ I heard about this algorithm second-hand: apparently there
+ was an article in _\bS_\bc_\bi_\be_\bn_\bt_\bi_\bf_\bi_\bc _\bA_\bm_\be_\br_\bi_\bc_\ba_\bn describing it some-
+ time in 1997.

+ _\bc_\br_\bi_\bt_\bi_\bc_\ba_\bl accepts the following options:
+
+ -\b-w\bwi\bin\bnd\bdo\bow\bw Draw on a newly-created window. This is the
+ default.
+
+ -\b-r\bro\boo\bot\bt Draw on the root window.
+
+ -\b-m\bmo\bon\bno\bo If on a color display, pretend we're on a
+ monochrome display.
+
+ -\b-i\bin\bns\bst\bta\bal\bll\bl
+ Install a private colormap for the window.
+
+ -\b-v\bvi\bis\bsu\bua\bal\bl _\bv_\bi_\bs_\bu_\ba_\bl
+ Specify which visual to use. Legal values are the
+ name of a visual class, or the id number (decimal
+ or hex) of a specific visual.
