What type of cellular automata is this?

So, this is kind of a long shot, but does anybody here familiar with cellular automata know what type this is? In the game, it starts as a flat pink/red and then becomes this over the course of a few seconds, and when like this it kinda just vibrates. I’m not sure what type or style of cellular automata this is though, other than the game itself is in the retro 8 bit style overall. If I’m asking this in the wrong place, I’m sorry. Looking forward to any answers!
