Q gets turned by a glider from behind:
x = 10, y = 9, rule = B3-ekqr4jz5cy6n/S2-in3-cekq4aw5-ce
8b2o$8b2o$9bo$7b2o3$2o$b2o$o!

Glider fuses:
x = 27, y = 24, rule = B3-ekqr4jz5cy6n/S2-in3-cekq4aw5-ce

o$7b2o$8b2o$7bo$4b2o$3bobo ...

This rule seems awfully familiar, but I can't put my finger on it. It isn't MirrorLife, or GliderGlut, but I've definitely seen that splitter and the Q.
Edit: I think it was a rule by dani. I've also seen that block eating reaction before.

Should all versions of the undimensional spaceship be merged into one page titled "Unidimensional spaceships"? I was thinking about including a general definition of a unidimensional spaceship being any ship with at least one 1D phase, then adding the known versions under a header named "History ...

Rules posted by hotdogPi do indeed seem to match the evolution in the video, with the exception of the bottom-right corner, which in the video pulsates constantly. This shouldn't be possible if every pattern moves to top-left, so it must be a hardcoded "spawner" of sorts? Unless it's a diagonal ...

Nvm then! I thought you coded that website or something

In Conway's Game of Life, each cell has 8 neighbors, but what if they had 4 on each side? Then you get "Static Life" which I've named. https://ncase.me/sim/?lz ...

Interesting -- though it'd be better if you'd zoomed in closer so we can actually discern the individual cells properly, and even better if you just put the RLE in tags so we can all view them.

By the way, who is "your team"?

I think this sort of thread fits better in the sandbox.

Today, i was hanging around in the Non-Totalistic OCA rule B3/S23-e4e in Golly when i accidentally created a spaceship while drawing. I do not know anything about the spaceship except its RLE and period, which is period 64. Could someone identify this spaceship, and tell me if its potentially a ...

Ok, but please don't create a whole new thread just to say that. The SL itself doesn't seem to be notable, so it would've been better to post it in the sandbox.

It's very large and the parts aren't even all connected, so I don't think it needs a name. It can be broken down into smaller, basic parts, however.
