This one comes from the code here from *Slackermanz*.

For this CA there are 4 different large size neighborhoods used each step.

Each cell uses the above neighborhood patterns to tally the live cells into 4 sum values. sum_0 is the live cell count in neighborhood 1, sum_1 is the live cell count in neighborhood 2, sum_2 is the live cell count in neighborhood 3, and sum_3 is the live cell count in neighborhood 4.

The sums are used to determine life or death for the cells by using the following formulas.

If sum_0 is between 0 and 17 then the cell dies.

If sum_0 is between 40 and 42 then the cell lives.

If sum_1 is between 10 and 13 then the cell lives.

If sum_2 is between 9 and 21 then the cell dies.

If sum_3 is between 78 and 89 then the cell dies.

If sum_3 is greater than 108 then the cell dies.

Put all that into an options form to allow easy config changes.

Here is a quick sample movie with a few of the interesting rules I found so far.
