'''Plow World''' is a [[Life-like cellular automaton]] in which live [[cell]]s never die, and dead cells are born if they have 3, 7 or 8 life neighbours.
'''Blinkers''' is a [[Life-like cellular automaton]] with [[rulestring]] B345/S2. Evolution in Blinkers usually stabilizes after a few hundred generations, leaving almost exclusively [[blinker]]s (hence the rule name) and rarely some larger oscillators.


==Patterns==
== Patterns ==
Because it is impossible for cells to die under this rule, patterns such as [[oscillator]]s and [[spaceship]]s cannot be constructed.
=== Still lives ===
No finite still lives can exist in Blinkers: if a pattern contains cells that have 2 live neighbours each (like a [[pre-block]], [[tub]] or [[beehive]]), it must always trigger either B3, B4 or B5 condition.


=== Oscillators ===
A [[blinker]] is the most common object in this rule, about 7.5 times more common that the oscillator from the 2nd place. 10 most common oscillators are shown below.


Oscillators with several different periods are known, the highest being p112.
=== Spaceships ===
Some spaceships in Blinkers were also discovered:

Blinkers is a Life-like cellular automaton with rulestring B345/S2. Evolution in Blinkers usually stabilizes after a few hundred generations, leaving almost exclusively blinkers (hence the rule name) and rarely some larger oscillators.

Patterns

Still lives

No finite still lives can exist in Blinkers: if a pattern contains cells that have 2 live neighbours each (like a pre-block, tub or beehive), it must always trigger either B3, B4 or B5 condition.

Oscillators

A blinker is the most common object in this rule, about 7.5 times more common that the oscillator from the 2nd place. 10 most common oscillators are shown below.

Oscillators with several different periods are known, the highest being p112.


Spaceships

Some spaceships in Blinkers were also discovered:


x = 8, y = 12, rule = B345/S2 4b3o$2bo2b2o$bo3bo$6bo$5ob2o$o3b2obo$o3b2obo$5ob2o$6bo$bo3bo$2bo2b2o$4b3o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ THUMBSIZE 3 ZOOM 21 WIDTH 500 HEIGHT 500 GPS 5 AUTOSTART TRACKLOOP 4 -1/4 0/4 ]]
