+    Displays the time evolution of elementary cellular automata.
+    
+    These automata consist of a line of cells, each of which may be either on or
+    off. To ensure every cell has neighbors, the two endpoints of the line connect
+    together, thereby forming a circular universe for the cells to inhabit. This
+    line is drawn horizontally on the screen.
+    
+    Over time, this line of cells evolves according to rules, with some cells
+    switching on or off. Each new iteration is drawn below its predecessor,
+    leading the screen to scroll vertically over time.
+    
+    The rules which govern the time evolution of this system depend only on the
+    current state of a given cell and the state of its two immediate neighbors.
+    These rules are formalized as Wolfram codes, where the code number is directly
+    convertible into a rule set.

 config via the file `~/.xscreensaver`. If preferred, it could instead be done
