Pentadecathlon
oscillator
Conway found it by running a row of ten cells. Period 15 - unusually long for something so small - and it emits sparks that make i…
Pulsar
oscillator
The largest common oscillator: 48 cells with fourfold symmetry, pulsing on a period of 3. Despite its size it turns up naturally i…
Beacon
oscillator
Two blocks touching at a corner. The facing corners wink on and off while the rest stays put.
Clock
oscillator
A four-fold symmetric period 2 oscillator that rotates a quarter turn each generation.
Figure eight
oscillator
Two 3x3 blocks that trade places on a diagonal every four generations.
Kok's galaxy

A pinwheel of bars that rotates through a period of 8. Named for Jan Kok, who found it in 1971.
Octagon 2
oscillator
An octagonal ring that pumps in and out on a period of 5.
Toad
