Recent work with Lenia, a continuously-valued cellular automata (CA)framework, has yielded $\sim$100s of compelling, bioreminiscent and mobilepatterns. Lenia can be viewed as a continuously-valued generalization of theGame of Life, a seminal cellular automaton developed by John Conway thatexhibits complex and universal behavior based on simple birth and survivalrules. Life's framework of totalistic CA based on the Moore neighborhoodincludes many other interesting, Life-like, CA. A simplification introduced inLenia limits the types of Life-like CA that are expressible in Lenia to aspecific subset. This work recovers the ability to easily implement anyLife-like CA by splitting Lenia's growth function into genesis and persistencefunctions, analogous to Life's birth and survival rules. We demonstrate thecapabilities of this new CA variant by implementing a puffer pattern fromLife-like CA Morley/Move, and examine differences between related CA in Leniaand Glaberish frameworks: Hydrogeminium natans and s613, respectively. These CAexhibit marked differences in dynamics and character based on spatial entropyover time, and both support several persistent mobile patterns. The CA s613,implemented in the Glaberish framework, is more dynamic than the HydrogeminiumCA in terms of a consistently high variance in spatial entropy over time. Theseresults suggest there may be a wide variety of interesting CA that can beimplemented in the Glaberish variant of the Lenia framework, analogous to themany interesting Life-like CA outside of Conway's Life.
