As previously discussed here, I am now starting a belated Pattern of the Year competition for 2014. It will be using the same voting system etc. as the 2017 competition, which I'll re-state once the voting starts.
Here are the entries that have already been collated (see also the wiki):
#01 Centipede (by Chris Cain): a large, engineered spaceship which moves at 31c/240 using a unique reaction.
#02 Dart and crab syntheses (by Martin Grant, Mark Niemiec, Michael Simkin, Ivan Fomichev, Tanner Jacobi, and Brett Berger): glider syntheses for small spaceships that previously did not have them.
#03 Half-baked knightships (by Adam P. Goucher, Chris Cain, Dave Greene, and Ivan Fomichev): large, engineered spaceships that move obliquely with displacement (6,3) and various periods using the half-bakery reaction.
#04 Pufferfish (by Richard Schank): a p12 c/2 puffer that was used to make the first wholly high-period c/2 spaceship.
#05 Spiral growth (by Dave Greene): a self-constructing pattern that grows in an outward spiral.
#06 Switch engine ping-pong (by Michael Simkin): a 23-cell quadratic growth pattern, which as of February 2018 remains the smallest known.
#07 Syntheses for all 17- and 18-bit still lifes (by Martin Grant, Mark Niemiec, and Matthias Merzenich): self-explanatory.
#08 Waterbear (by Brett Berger and Ivan Fomichev): a large, engineered spaceship, which moves at (23,5)c/79 and is thereby the first (and, as of February 2018, the only) fast oblique spaceship.
#09 Weekender distaff (by Ivan Fomichev): the first 2c/7 orthogonal rake, consisting of a long chain of weekenders perturbing debris.
From the time of posting, I will allow a period of 48 hours (which could be extended if there is sufficient interest) for people to propose any additional entries before the voting starts.
Additional entries (EDITed into the post):
#10 Honey thieves (by Matthias Merzenich): the smallest known p17 oscillator, and the first one with a known glider synthesis.
#11 p27 billiard table oscillator (by Matthias Merzenich): an oscillator in which p5, p8 and p3 rotors phase shift each other.
#12 LCM oscillators (by Noam Elkies): oscillators featuring multiple rotors that interact in complicated ways.

A central p5 rotor and 4 auxiliary p8 rotors phase shift each other. This would ordinarily result in a p17 oscillator, but p3 rotors at the outer edge shift the p8 rotors twice, creating a complicated p27 oscillator.

Okay, I'll do that for the 2012 and 2013 competitions. But, in this case, because there was already a list of entries from the earlier iteration of the competition and no-one responded in this thread except Sokwe (who did so soon after I opened the thread), I thought no-one else wanted to nominate anything (and I did say I'd extend the nomination period if there was sufficient interest).
I've added them to the main post.
