Thanks. This definitely seems like it should be on LifeWiki. Would it be appropriate to use your post as a citation?

### Re: Euclidean CA (ECA)

A cell with maximum heat would be surrounded by infinitely many cells. This 'maximum heat' number is finite, but I do not yet know its value. A 511x511 block of cells yields the number 6.0267726589419..., but that's not even close to a good estimate. I have settled on using 7 when engineering day a...

I asked for this before, but it got misunderstood, so I'm gonna try again. I want a way to take a normal life-like rule, say B3678/S01245 (just an example) and run it so instead of the cells all updating simultaneously, they update in a specific asynchronous fashion. The way cells should update is a...

### Re: image oscillator?

It would be an oscillator if you could construct a rule it works in. Unfortunately, that doesn't appear to be possible, even with extended neighborhoods. See, when the dot hits one of the circles, it gets eaten. This means that the circle goes back into a steady state and has no reason to emit a do...

There is such a script here, however it only handles semi-totalistic rules.
