I broke it. (In a good way) I managed to embed a pattern in the feed that is not repeated in the output. Well, at least some of the time is not repeated-haven’t done very many iterations.
That might be due to the blue rect and the green rect must be separated with a straight line, and straight lines are hard to come by: https://imgur.com/85W15eI
I broke it in a bad way. Pattern chugged along fine and then it froze and a random white rectangle appeared. (N=3)

Ah, sorry I didn't make that clear... That would be a contradiction, as no pattern was found to fit in that area. You need to generate again.
Interesting. Well it only happened once so I guess I just got bad luck. Fun demo!
