Notes on Implausible odd triangles

This one build upon the rootlike idea but heaving odd. For some reason these patterned and empty triangles appear from the otherwise completely random and unpredictable background pattern. And which ones get to be patterned or empty, whatever decides that, might be even more mysterious to me.

Though very mysterious (though? It's not a bad thing) I must say that it is definitely one of the cooler cellular automata!
