Here is the list of entries for the competition:

• #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.
• #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.

We will use the same voting system as the 2016 and 2017 competitions:

Vote only for the patterns you like, and give each of them 1, 2, or 3 stars depending on how much you like them. You can vote for your own patterns if you want. Here is an example vote:

#01 *
#02 **
#04 ***
#08 *

The voting will close two weeks after the creation of this post.

EDIT: Voting is now closed!

For the sake of transparency, I will cast my own vote first:

#01 **
#03 **
#04 *
#06 *
#08 ***
#09 **
#10 *

#01 ***
#03 ***
#04 *

#11 ***

I do not remember much from that year so I will give what seems like a pretty underrated choice the only vote.

A reminder: there is now one week left to vote in this competition!

Voting is now closed. I'll announce the results soon!

Here are the results of the belated Pattern of the Year 2014 competition! We have three ties.

1. Waterbear (#08) (30 stars)
2. Centipede (#01) (23 stars)
3. Half-baked knightships (#03) (21 stars)
4=. Switch engine ping-pong (#06) (17 stars)
4=. Syntheses for all 17- and 18-bit still lifes (#07) (17 stars)
6=. Pufferfish (#04) (13 stars)
6=. Spiral growth (#05) (13 stars)
8=. Dart and crab syntheses (#02) (12 stars)
8=. Weekender distaff (#09) (12 stars)
10. Honey thieves (#10) (8 stars)
11. p27 billiard table oscillator (#11) (7 stars)
12. LCM oscillators (#12) (6 stars)

I'm surprised that the Dart and Crab syntheses ended up so low. They seemed like such a big deal at the time. The construction of small spaceships has always been one of the most sought after results in glider synthesis research, and these patterns represented a significant advance in that technology. By comparison, the synthesis of 25P3H1V0.2 seemed to do better in 2017. I wonder if they would have done better had the competition been held back in 2015.

I agree. Also the pufferfish may seem like something self-evident in 2018, but in 2014 it was a really huge excitement. It would be definitely higher in my leaderboard.
