### Re: Rules with interesting dynamics

In a rule for a 23-cell 6c/3946o from the 5S, shrinking spaceships emerge: x = 11, y = 12, rule = B3air4ejk5kny6ci8/S2aek3-aek4ceity5acejr6kn78 b2o$obo6bo$2o6b3o$7b2obo4$3bo$2b2o$b2o2bo$2bo2bo$4b2o! snip This rule is explosive, but the explosions also look quite interesting, almost like a reploop r...

### Re: Does this pattern approach a perfect circle?

It's difficult to say. After 50,000 generations it looks a bit more like a 16-gon than a circle, though, but it's possibly that's just aliasing and a larger number of generations might give a different result.

### Re: Miscellaneous Discoveries in Other Cellular Automata

This rule has has a family of extendable diagonal oscillators whose periods increase and decrease irregularly. The sequence the periods follow doesn't look familiar to me, but the diagonal oscillators clearly are emulating a sort of 1D CA with maybe four states. x = 64, y = 17, rule = B3-jq/S1c2-i3-...

Those are both fascinating oscillators. The first one looks almost like an RRO of an RRO - an RRO-like structure that doesn't quite return to its original position but instead "rotates" slightly as a whole, it's hard to describe. Visually, it's movement reminds me of that of cyclones. The second one...
