CheckerboardPedestrianLife
A checkerboard rule with a variety of speeds including 7c/171o, (1, 7)c/14 and a common photon.
There is also a diagonal rake and orthogonal puffer. The latter can be corderised to form a P24 photon.
In addition, a handful of oscillator periods have been found with the most common being the rotating P24.
