Second-order cellular automaton

learned about Second-order cellular automaton.
basically, you consider a cell's previous-previous history, instead of just previous.
in this way, the cell's state can be considered as a recurrence relation.

block cellular automata

learned a new thing. block cellular automaton.
you group the cells into blocks.
cell in a block is considered its neighbors.
but in each generation, you shift the grouping blocks.
