Karel's p15

Karel's p15 is a period-15 oscillator discovered by Karel Suhajda on December 11, 2002.[1] It consists of a period 15 rotor supported by the domino spark of a pentadecathlon. A pentadecathlon can support 2 Karel's p15s. It provides accessible sparks that can be used to perturb reactions. The p15 bouncer mechanism is an example. In the same month of its discovery, Mark Niemiec found an 18-glider synthesis of this oscillator.[2]
