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