Automat

Automat is a cellular automaton viewer. Each pixel in the automaton's canvas can either be black or white, and a pixel's color is set based on the colors of the three adjacent pixels above it. The eight diagrams in the control bar show the system's rules. You can change the output value of each rule by clicking the single square below the three inputs. Run and enjoy.

This sketch was created to visualize the examples in Stephen Wolfram's New Kind of Science.

Here are a few sets of rules to try:

1. 
   This set of rules produces a very simple pattern. You'd
   probably expect that this is about the level of complexity
   that can be generated with such simple rules.

2. 

3. 
   The patterns generated by the above two set of rules
   are slightly more complex, but still show a large degree
   of regularity.

4. 
   Wildly unpredictable output is also possible, however. This
   set of rules generates a pattern with a band along the left
   side and regularly occuring diagonal stripes, but there is no
   discernable pattern in the way the branch of larger triangles
   moves through the center.
