Fumarole is a period 5 oscillator that was found by Dean Hickerson in September 1989. In terms of its 7×8 bounding box, it is the smallest known period 5 oscillator. On September 1, 1995, Noam Elkies found a way to non-trivially combine two fumaroles and a blinker into a period 10 oscillator, shown below.
