Smiley is a period 8 oscillator that was found by Achim Flammenkamp in July 1994 and named by Alan Hensel.
In November 1994 Mark Niemiec noticed that its sparks can interact in boring, but non-trivial ways with other oscillators, optionally creating oscillators of higher periods.[1]
Synthesis
A 28-glider synthesis for it was discovered in January 2008 by Jason Summers.[2] In August 2015, Matthias Merzenich proposed an 8-glider synthesis based on a soup found by Adam P. Goucher using apgsearch.[3]
Commonness
On Catagolue, it is the fourth most common period 8 oscillator, being less common than Coe's p8 but slightly more common than Achim's p8.[4]
