B024/S1V

Today I have been exploring B0 rules with von Neumann neighbourhood. I thought that something interesting could show up, and indeed I was rewarded by... a spaceship!
Code: Select all
x = 2, y = 3, rule = B024/S1V
2o2$o!
This creature frequently occurs naturally. It travels at c/2 orthogonally.

By the way, happy 14th birthday to Aidan F. Pierce!

Simple oscillators:
Code: Select all
x = 121, y = 7, rule = B024/S1V

I once wrote a custom Java application (which I have long since forgotten) to explore such Von Neumann CAs. I found that this was not one of the more interesting rules. Now that I have come back here, here are four little oscillators.
Code: Select all
x = 19, y = 21, rule = B024/S1V

Could you publish those "more interesting" rules? I have actually looked at all von Neumann CA that could theoretically support spaceships. This was the
only rule with a natural spaceship I have found. Have I overlooked something?

Well, sorry, that program was written as a computer science module assignment (in Java). And I didn't note down the interesting rules, the teachers were just interested in the coding. And I deleted the application after the module was over.

Two spaceships interact non-trivially:
Code: Select all
x = 2, y = 8, rule = B024/S1V
2o2$o3$o2$2o!
Here is a wick:
Code: Select all
x = 79, y = 1, rule = B024/S1V:T80,0
