Rattlesnake is a period 11 oscillator found by Dean Hickerson on January 10, 2016^{[1]}. In terms of its 33 cells, it is currently the smallest known period 11 oscillator. It gives 2 sparks: one on the right and one on the left, and this allows the construction of higherperiod oscillators.
Martin Grant found a 37glider synthesis of this oscillator no later than January 13, 2016.^{[2]}
