Add other LWSS emulator, which seems appropriate to put here, being that it isn't linked to any article by Catagolue and that the Emulators article links here for p5 LWSS emulators, so it is where people would go to look (terribly sorry for previous premature edit, I pressed the enter key by accident and am using my smartphone)

Toaster (or lightweight volcano) is a period-5 oscillator that was found by Dean Hickerson on April 1, 1992[1] that produces sparks much like a lightweight spaceship on its left and right sides. Minimal changes can be done to change its symmetry type. It contains three separate rotors: two copies of a basic sparker, mutually stabilized with the aid of a siesta variant encased in its center. The 42 and 53 cell variants upgrade this to an actual weld of the sparker engine with additional p5 components.

Generation 4 of toaster reveals its sparks

On November 19, 2021, Dongook Lee and Entity Valkyrie observed that a toaster can be phase shifted to produce an oscillator of period 5n + 2.[2]

Commonness

A stator variant of this oscillator appeared semi-naturally on April 27, 2018, in a symmetric soup submitted to Catagolue by Apple Bottom[3], and another on February 16, 2022, by Charity Engine[4].

As of May 30, 2023, no variants with less than order-4 symmetry have occurred seminaturally.

Variants

There exist multiple smaller oscillators that give off LWSS sparks on only a single side.
