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. A minimal change can be done to change its symmetry type.

Generation 4 of toaster reveals its sparks

A stator variant of this oscillator appeared semi-naturally on 2018, in a symmetric soup submitted to Catagolue by Apple Bottom[2], and another on 2022-02-16 by Charity Engine[3].

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.[4]

Multiple smaller oscillators with only single LWSS sparks also exist.
