Ocellus is a period-114 oscillator, being the second-smallest example of a relay construction using p6 thumbs allowing all oscillators of periods 90 + 24n to be constructed with 92 cells. It was formerly the smallest known p114 oscillator, until the discovery of caterer on 44P38 in 2022. It uses Michael Simkin's reduction of Noam Elkies' 180-degree reflector.[1] A glider synthesis for this oscillator was found by Jeremy Tan on September 5, 2021.[2]
The underlying reaction can be supported with many oscillators that emit a dot spark, as shown below:

| Gallery of 3-block-1-tub periodic 180-degree reflectors. From top to bottom, left to right:
p4, using a middleweight emulator variant for higher clearance to allow glider input.
p5, using a 37-cell p5 thumb.
p6, using a p6 pipsquirter. P6 thumb can be used to reduce the population, and is used in Ocellus
p7, using a thinner p7 pipsquirter variant, 34P7 can be used to reduce the population. The 34P7 variant is used in Gallus.
p8, using a blocker.
p10, using 55P10.
p12, using Eye of Sauron.
p14, using 34P14 shuttle. It can also be used in Gallus.
p15, using Pentadecathlon.
p22, using Jason's p22.
p30, using buckaroo.
p46, using Tanner's p46.
