Clock 2 is a period-4 oscillator. It is a billiard table configuration with the same stator as pinwheel.
On April 22, 2016, Martin Grant provided a glider synthesis for this oscillator. Using the same precursor, the two routes to clock 2 and pinwheel diverge in the middle.[1]
On January 27, 2024, 400spartans showed that an agar containing clock 2 rotors is self-forcing, so has no predecessors which are agars of the same spatial period.[2]
