Game of Life Cellular Automata 4+

Or maybe not really even the basics. I could not find a way to restart or back up a sequence. It ran, it was over. Made it difficult to do repeat experiments. The demonstrations are interesting. Good that it’s free (somebody’s early project?), but I’d be willing to pay a couple of three dollars for a version of this with some experimental controls, if you know what I mean.🤔😉😊

How to make:
Building size: 9x9
Vertical:build at the 5th column a 3 then a gap by 1then 1 then a gap by 1 again then a 3.
Horizontal:build in the 5th row and build 3 squares (there is that middle peice again so I consider the next gap a 3 so put the gap in there) and then put The last 3 blocks in.
Press the play button and volia!

Valve:
How to make: it is simple!
Size: 4x2 or 4x4
4x2 version: put 1 square on the top for the 1st column, put 2 squares on the 2nd and 3rd columns and last but not least, put one more square on the bottom of the 4th column.
4x4 version: put two pieces in the exact middle for the 1st column then for the 2nd column put one on the top, for the 3rd column put one on the bottom, and for the fourth and final column, do the exact steps from column 1. Done!

Carriage:
Size: 3x3
How to build: put all three squares in the 1st column but the 2nd column requires you to put squares in the top 2 northern spots, and we move on to the 3rd column which requires you to repeat the steps from the 1st column

This is an awesome simulator. Some things that would make it even better:
- it would be really cool to be able to save custom creations
- the grid becomes invisible when zooming out too far, especially on the larger boards. It would be nice if it were always visible, or even if there was an option to make it visible or not
- it seems to count every square manually placed as an iteration, which should not be the case
- it should start out in the center of the board instead of the top left. I always find myself zooming out and finding the center manually so that the walls are less likely to affect the results

(I am using the app on an iPhone 12 Pro)

All that said, this is a really nice and charmingly simple app :)
