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

It is commonly used as a sparker, for example in some variants of p48 pi-heptomino hassler and pi orbital. 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.

Martin Grant found a 81-glider synthesis for this oscillator on January 5, 2015. This was improved to 79 gliders by Matti Ward on February 17, 2018, followed by 62 gliders in June 2019 due to incremental reductions by Jeremy Tan, BlinkerSpawn, Goldtiger997, and Luka Okanishi. GUYTU6J reduced the synthesis further to 54 gliders in February 2020.
