OCA:HighLife/p24 shuttle

Main article: OCA:HighLife

The p24 shuttle is an oscillator discovered by Dean Hickerson in 1994. If left unassisted, the active region flips in 12 generations and produces a spark (which is a traffic light predecessor in Life). The spark then interferes with the evolution of the active region and prevents it from flipping again, though it can be suppressed using an eater 1 or other mechanisms. Thus, the minimal form of the oscillator is basically the active region traveling back and forth between the two eaters.
