Oh well! I should have looked more carefully. Thanks for pointing that out, that's a beautiful puffer!

Here is an interesting rule featuring the naturally occuring:
3c/5 spaceship
x = 5, y = 5, rule = R2,C6,M0,S2..3,B3..3,NN
2.A$5A$.3C$BCDCB$E3.E!

(5, 7)c/21 knightship
x = 5, y = 5, rule = R2,C6,M0,S2..3,B3..3,NN
3.ED$D4E$DA2E$2A2D$2A!

and most importantly this "spaceship-like" p124 oscillator ...

After a long time playing around with Star Wars I decided to try and find the "simplest" rule to support the same kind of signal circuitry, this is the one I found most interesting.

All the things I build are based around these "double crosses" circuits.
x = 54, y = 6, rule = 34-ik5e/2ace/3
2.A4 ...

Another stable rule
A diagonal c/2
x = 8, y = 7, rule = R2,C4,M1,S4..4,B4..4,NM
3$.3A$4.A$4.A!


3c/2 Spaceships similar to the photons of rules like Star Wars, they can be extended or perturbed to produce a large spark
x = 16, y = 38, rule = R2,C4,M1,S4..4,B4..4,NM
3$5.A$6.2A$8.2A$8.2A$6.2A$5 ...

Soooo stoked for having LtL in golly! Great job!

You can do this with a rule table, using the neighborhood Moore_radius2: https://code.google.com/p/ruletablerepository/wiki/RoadMap
I don't think it's implemented in the current version of Golly.
It would be interesting to know if, say, Von Neumann with radius 2 could be implemented in the normal ...

Nice rule, I found a wick!

Nice rule! I've been playing around for about an hour! (whyyy)

Nice looking rule!
It seems a bit difficult constructing spaceships though

A basic symmetric diagonal C/3
x = 5, y = 5, rule = aurora19
2.2A2$A2.2A$A.A$2.A!

Which can be extended indefinitely
x = 11, y = 11, rule = aurora19

Imagine that the neighborhood of a cell changes with the cell's position, in the following lattice:

A B A B A B A
B A B A B A B
A B A B A B A
B A B A B A B
A B A B A B A


The A cells and B cells have these neighborhoods:

O O O
O A O O B O
O O O

I'll need to read this topic thru again with more attention, but am I getting the gist right: basically this is a 2D emulation of a totalistic CA running on a 3D grid infinite in two directions but having a width of just two in another?

Yes, that's the idea!

Here's b(4,6-2)s(1-)

Here are some rules:
n_states:3
neighborhood:Moore
symmetries:permute
# UNAMED RULESPACE
# A state-0 cell counts as 0 cell
# A state-1 cell counts as 1 cell
# A state-2 cell counts as 2 cells, therefore it adds +1 to the neighbors count
# It can be extended to even

# Example rule: b(3-2)s(3,5-2,3 ...

Here's an update:
since I failed at writing a rule generator, I decided to manually write the general ruletable for this Rulespace.
Here's how it works:
•In the Life-like Rulespace, the next state of a cell is determined by the number of neighbors,
but in this Rulespace the next state of a cell is ...

Very interesting! I love exploring new strange rulespaces, but there seems to be a problem with the General-Bx2 and Tripod-Bx2 rule generators (at least on my computer):

• The rule is succesfully created but I can't load any of your patterns, golly always give me this error File could not be loaded ...

Mcell is more convenient.Although golly can support all types of CA,but we don't need them.
What do you mean with "we don't need them" ?

What's more convenient about it? And why should we limit ourselves to CA that mcell can represent? Or to naive step algorithms rather than hashing? Or a finite ...

First, I wonder if there if it would be easier to not count the central cell, and simply rely on the Birth/Survival rule specification. In Weighted Life, the ME value turned out to be superfluous; doesn't it here too?

No, that's an integrant part of the Rulespace! I'm sorry, maybe I didn't ...

Thank's for the feedback, I really appreciate it.
Since I'm far from being an expert programmer, I surely have done some errors...

I first started looking into this Rulespace in a python program I wrote myself on holiday, and, since it worked in a completely different way from the Golly's ...

Some example rules:
b3;3s23;23 (double GoL)
I found an orthogonal c/2 and a diagonal c/10:
x = 4, y = 10, rule = b3;3s23;23
A2.A$AB.A$A5$2A$AB$3A!


b3;3s23;23 (the first rule I explored)
An orthogonal c/2 and an orthogonal 2c/9:
x = 6, y = 19, rule = b3;2s35;23

During this summer, I thought of a rulespace in which every cells is counted depending on its state.
For example:

1 1 1
0 0 1
0 0 0

The center cell has four state 1 cells around, so its neighbors count is 1+1+1+1 = 4


1 2 1
0 1 0
0 0 0

The center cell has two state 1 and one state 2 ...

Do the B6 and S6 actually do anything? All of these patterns seem to work almost identically in /24/3.
Brian 6 seems to be a little more dense than Brian's Brain, but the two rules are almost identical...

Just for curiosity's sake, I calculated the density of the smallest exploding seed after ...

Thanks for all the explanations, everything's much more clear now. One of my favorite rules is Midges:
it has two simple c/2:
x = 17, y = 2, rule = Midges
3A10.4A$3B10.4B!


And very simple guns:
x = 21, y = 2, rule = Midges
5A10.6A$5B10.6B!


The 'dot' still life I found can be easily moved by ...

I don't understand very well how weights work. When it's set to 0, the neighborhood is not counted, and that's how you emulated the Hex rule. When it's set to 1 it's like a totalistic rule's neighborhood. But how does it work with higher numbers?
However thanks for your work, I'm so happy that we ...

Just wanted to share: seems really interesting!
