|Simkin glider gun is a glider gun, found by Michael Simkin on April 28, 2015. It consists of a Herschel running in two period-60 conduits, producing infinite copies of the first natural glider. In terms of its single-barreled form it is the smallest known gun, with 36 cells, sharing the record with the Gosper glider gun. In its pseudo-period, boat-bit form and its double-barrelled form it is the absolute record holder, with 35 and 29 cells respectively.

|The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:
Did you know...
- ... that the first glider synthesis for a c/3 spaceship was completed in 2014?
- ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015?
- ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships?
- ... that there are no known direct reflectors for lightspeed wire signals, or for signals in 2c/3 wires, but that very large reflectors for these signals can be constructed using stable or periodic circuitry?
- ... that 24 ten-cell patterns exhibit infinite growth, with 17 unique pattern types, but that it has been proven that no nine-cell pattern exhibits infinite growth?
- ... that all still lifes up to 19 bits have a known glider synthesis, but it is still not known whether all still lifes are synthesizable?
- ... that the French kiss remained without a glider synthesis until 2013?
- ... that Adam P. Goucher's distributed Catagolue soup-search project, started in February 2015, has tested several orders of magnitude more random soups than any previous such project, and has contributed to the reduction of many glider construction recipes?
- ... that with the appearance of the 0E0P metacell, the number of periods for which strict volatility 1 oscillators were known went from 12 to infinity?
- ... that Copperhead is not only the first c/10 orthogonal spaceship ever found, but also remarkably compact for a pattern not discovered until 2016?
