44P12.3 (or Eye of Sauron[1]) is a period-12 oscillator discovered by Nicolay Beluchenko on March 26, 2009.[2][3]

It is commonly used as a sparker. On January 12, 2019, Tanner Jacobi used it along with dueling banjos, a heavyweight emulator variant, and pipsquirter 1 to build a period 24 glider gun which was then optimized by Matthias Merzenich the next day to be smaller than the previous record holder.[4][5]

Martin Grant found a 81-glider synthesis for this oscillator on January 5, 2015.[6] This was improved to 79 gliders by Matti Ward on February 17, 2018,[7] followed by 62 gliders in June 2019 due to incremental reductions by Jeremy Tan, BlinkerSpawn, Goldtiger997, and Luka Okanishi.[8][9]
