Gosper glider gun
The Gosper glider gun is the first known gun, and indeed the first known finite pattern with unbounded growth, found by Bill Gosper in November 1970.[1] It consists of two queen bee shuttles stabilized by two blocks. Its 36 cells remained the smallest size of any known gun until the discovery of the double-barreled Simkin glider gun in 2015 which overtook this record with only 29 cells.

As the Gosper glider gun can be constructed with only 8 gliders, it has the smallest known glider synthesis of any gun. It can be destroyed completely by 2 gliders, as shown below.
