Replicator is an amazing rule to me. how it can clone any input, and how the middle just knows when to dissapear, its amazing. now we will look at its variants. hooray?
the only rule facilitating stable patterns (due to the absence of the B1 transition, which causes omnidirectional lightspeed explosion), it is unusual because random soups act a bit like Life (albeit with a tendency to explode slowly and chaotically)
