One is for ArrayPlot, the other is for Show. If you put a semicolon after the end of ArrayPlot or if you jut leave out Show, you will have just one plot. Mathematica has the built in function CellularAutomaton. For example: In[6]:= ArrayPlot[CellularAutomaton[ 110, Join[Table[0, {i, 1, 500}], {1}], 500]] will show a nice plot of the rule 110 cellular automata started from one black block on the upper right hand side.
