WHAT IS IT?

This model demonstrates a single rule of a 1D cellular automata. Cellular automata are a simple set of 'settings' that that can produce complex behavior. There are eight 'settings' that can be set to "on" or "off" thus making 256 possible rules. This particular model is set to rule 106. A patch is "on" when it is green and black when it "off". The program starts with a single row of patches and affects the cells in the row below and based on the particular rule. In this particular model, the patch color directly beneath a certain patch is determine based on whether the patches 8 spots to this certain patch's left and right are on or off.

HOW TO USE IT

Click the SETUP-SINGLE button to create one patch that is on. Click the GO button to begin implenting the rule.

THINGS TO NOTICE

Notice the complex pattern that is created from implenting these simple settings in this rule.

THINGS TO TRY

One can change this particular rule back to its normal setting and observe a different pattern. To do this, you must go to the procedure tab, and in the to do-rule command, set left-pcolor and right-pcolor to -1, 0 and 1, 0 rather than -8, 0 and 8, 0.
