The following movies show up to iteration 127 of various Boolean automata with hexagonal symmetry applied to an initial configuration consisting of an isolated point. The first movie shows Wolfram's model [1]. The other movies follow more complex rules that nonetheless preserve hexagonal symmetry.

Wolfram's automaton	Automaton with hexagonal symmetry (rule 25629998)
Automaton with hexagonal symmetry (rule 27541687)	Automaton with hexagonal symmetry (rule 32824527)
