This cropped up (or rather, a close variant) while I was looking at the debris behind a line puffer (with various 'obstacles' placed). Not seen one of these before:
x = 10, y = 9, rule = B3/S23
4b2o$2o2bo3b2o$o8bo$b8o2$b8o$o8bo$2o2b2o2b2o$4b2o!
Interesting because it has a rotor of just 3 cells ...

This rule could do with more investigation! I've noticed that the R-pentomino (the only methusaleh pentomino in Conway) explodes in this rule - maybe the smallest exploder in Dotlife? And the resulting splodge emits plenty of those "stabilised B-heptomino" SS's - as well as stable versions of the ...

Thanks guys for the info. Yes I do have Golly (wish it had a different name though :? ) - but I certainly haven't learnt all its clever stuff yet! Also the simpler and less sophisticated Life32. I use them to play around with random patterns, hoping 'something will turn up'.

Anyway it wasn't too ...

Hello. Newbie here, no expert on Life, just enjoy watching stuff evolve without really understanding it!

I was just playing around with the rule B367/S245, starting from random fills, and I noticed that this long-period oscillator crops up very frequently:
x = 6, y = 2, rule = B367/S245
o4bo$b4o ...
