Replicator made of two constellations from one of my old rules, very clean for some reason?

Very cool gun imo in a rule with very weird dynamics:

By "no programming languages", I mean no external programming to search for, generate, transform, or control the solution. Manually searching existing rules or patterns is fine.

Could anyone search 2-a3-ce4ekrtwyz78/2ce3i78/3 on any symmetry? I've noticed quite a few different ships and a RRO.

Hello!
Today I found the interast thing for Star Wars rule.
I want to name it "Empire": this is so fragile and in here so much spaceships are dies and so much trash lefts. One side has an energy shield, but other doesn't.

What do you mean by no python, lua, ada, and other languages? as in they cannot be used to identify patterns, so we would need to manually search? also, is this challenge limited to life or also to OCA? And also, with all due respect, why this specifically?

If OCA is allowed, I'll assume LtL is ...

Even after all these years, I still don't know what is categorized as an "Interesting" rule by the general community. I also recently tried rulegolfing a rule with engineering potential, with moderate to little success:

I mean... Golly doesn't take that much programming either.

This rule which has occasional growing ships that are relatively rare, but become pretty common in 1000x1000 soups.

My end goal is kinda to just to make a ship that can grow a stable agar.

Nevermind, I lost it. it was a small head that grew on one side and grew to I think a little more than 100 cells wide, and then stopped. it was very very large and natural.
