A simple rule with much potential:

Code: Select all

x = 0, y = 0, rule = B2-ac3/S24a
!
[[ RANDOMIZE ]]

There are two RROs in this rule. One is a “glass-tile” p28 and the other is a sparky p68.

It is possible to combine two of the p68s to make a gun.

It is also possible to prevent the gun from working by colliding a spaceship with it from behind, thus creating a functional NOT gate:

Code: Select all

x = 28, y = 33, rule = B2-ac3/S24a

We just need to find the stripe dual of this rule.

Well, figuring that out for strobing rules is HARD, so I added S8:

Code: Select all

x = 16, y = 16, rule= B1e2i3jy4aqtw5a6k/S012eik3r4aqrw8:T256,256

Here it is!

2o$2bo!

If you want the rule to have spaceships, then you unfortunately have to add a lot more conditions to the original rule:

Code: Select all

x = 16, y = 16, rule= B1e2i3jy4aqtw5a6k7c/S012eik3r4aqrw5ai6a78:T256,256

The behavior is still similar though!

Code: Select all

This rule has some interesting patterns, including two bobs having a conversation and leaving behind some thoughts:

not sure what to call it, but this rule has cool looking ships, some of which can produce MORE cool looking ships
it also has these doohickeys, some of which produce continuous laserbeams or even waves that assume the shape of a rectangle... these doohickeys also reflect or absorb lasers while staying stable oscillators
its kinda similar to the StarWars rule

Are generations rules just not as welcome? (I almost do only generations rules)

Generations is somewhat underinvestigated, yes. But all CA is welcome here

I engineered this rule so that this agar and its extensions are indestructable:

Code: Select all

x = 16, y = 17, rule = B2cek4ent5an6ci7e8/S12e3ejkr4-acnqy5-aei678

bo3b2obob2o$obob2o3bobobobo$o2bobo3bo2bo2bo$6o3b7o!

I call these 'null zones'.
The rule also has a c/4d, and has a common failed quadratic replicator:

Code: Select all

x = 9, y = 3, rule = B2cek4ent5an6ci7e8/S12e3ejkr4-acnqy5-aei678

A wave:

Code: Select all

x = 22, y = 22, rule = B2cek4ent5an6ci7e8/S12e3ejkr4-acnqy5-aei678:T22,22

Switch-engine-like stabilization of the replicator into a puffer (not corderizable, sadly)

Code: Select all

x = 28, y = 23, rule = B2cek4ent5an6ci7e8/S12e3ejkr4-acnqy5-aei678
