Cha cha[1] is a period 2 muttering moat[2] oscillator, the long extension of clock.
As of February 2022, this is one of eighteen 16-cell oscillators which are yet to arise naturally from an asymmetric soup on Catagolue.[3] However, this is a somewhat unique case, as on July 11, 2022, Charity Engine found a symmetric soup that produces this oscillator in an asymmetric manner. By using the same seed for a C1 soup, an asymmetric soup producing cha cha can be made, making it ambiguous whether or not this oscillator qualifies as "natural".[4]
All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
