would like to see a live animation of this

Maybe I'm getting this wrong, but in my understanding is that since with this configuration it must be the same for T amd T-1 one and so must already exist from the beginning. There is no state other than itself that leads to it.

So the still image is already the animation of it ;)

I made an animation [0] by taking the given pattern and finding a 3 step predecessor of it. In accordance with the theorem the pattern is still present in the predecessor. So you can watch the other cells churn around it without changing the central region.

Just off-hand, this looks like a great way to build long-period oscillators.

Lots of people will miss the joke.

With this audience, that joke just fell flat and stayed there for all time.

The joke was so bad that it never even stood up, it just is and always has been dead.

It is interesting to see what's happening around this pattern, so I won't be too sure that it was indeed a joke.

I don’t think it is for this discussion. You could put any pattern around it that doesn’t soon destroy this pattern (I would pick one that eventually destroys it. That takes away any possible misunderstanding about this pattern being indestructible)

Also, I think there’s no animation that shows the special property of this pattern.

Yes, you could show a grid with all other possible 30 × 24 cell grids, iterate over one iteration, and then show none of them evolves to the given pattern, but that grid would be way, way, way, too large (and that’s an under-, under-, understatement) for that to pop out (that’s a scientific term. See https://en.wikipedia.org/wiki/Visual_search#Feature_search) to our visual system.

It's missing an "/s" at the end to make it passable
