New rule:ylife(B34y5y/S234y5y).
Rule is mainly of interest due to stairstep hexomino,that is exploding oscillator with period 17(if I counted correctly) with volatility 1 and with lots of easily acessible sparks. It seems very useful. I also have found a very interesting reflectorless rotating oscillator. Despite all of them,it is relatively calm and much less dense than game of life. Most of the standard objects are still working.
Please try it!
