Simple nested patterns are common.
Notice that the patterns can grow only to the right, due to range 1/2.
Behaviors seen in some rules are repeated in others that are equivalent under a color rotation.
More complex behaviors are seen from simple initials in rules 38 and 61, for example.
Some rules, like rule 100, show particularly complex behavior from random initial conditions.
Rule 106 shows simple particles from simple initials, but complex interactions among multiple particle types from random initial conditions.
