Lightweight emulator is a period-4 oscillator found by Robert Wainwright in June 1980[1] that produces sparks similar to those produced by the lightweight spaceship. It is the smallest and least useful of the three standard emulators.
This oscillator first appeared semi-naturally in September 2016.[2] A 13-glider synthesis is known for a stator variant featuring loaves in place of eater heads.
