I have been exploring a variety of cellular automata lately and here is another one.
This is from another idea I had. I am not sure if this is unique, but a quick hunt found no matching CAs. If it is a duplicate of an existing named rule, let me know.
This is a totalistic CA that uses the usual 8 immediate neighbor cells as well as the last step’s current cell and 8 neighbors. This gives a total of 17 neighbor cells that can influence the birth and survival of the cells.
I call them “History Dependent Cellular Automata” because they depend on the previous cycles’ neighbor cells as well as the usual 8 immediate neighbor cells.
Here are a few animated GIFS showing some early results. The GIF thumbnails are messy, so click them to see the clear GIFs.
The CA is now a new mode included with Visions of Chaos if you want to have a play with it.
