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.

A stator variant of this oscillator appeared semi-naturally in April 2018, in a symmetric soup submitted to Catagolue by Apple Bottom.[2]

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.[3]
