p11 domino sparker is a period-11 oscillator discovered by Martin Grant on June 17, 2021. It is the only known p11 domino sparker. Despite the name, it also has uses as an edgy dot sparker by using the vertical edge of the domino.

It has very low clearance, and it is a delayed domino sparker, so it has few uses. However, it can be used in the p11 bouncer, which gives a repeat time of 22 ticks, the minimum possible for any bouncer.
